What are the first four terms of the sequence represented by the expression n(n-1)-5?
No dude, I'm pretty sure the answer is D.
Y’all realize everybody has different tests right? You need to find a answer from each question
The choices are
-7,-5,-3,1
-5,-10,-15,-20
0,2,6,12
-5,-3,1,7
I don't understand how to do this at all. Please help!
I think the answer is
-5,-3,1,7 for question 3
Anyone knows the full test??
Y'all do know the test changes right?
The general term is
Tn = n(n-1)-5
So, for n=1,2,3,4,5,... replace each n by the given value. That gives
T1 = 1(0)-5 = -5
T2 = 2(1)-5 = -3
T3 = 3(2)-5 = 1
and so on
I am confused... is that the equation n(n-2)-3??? so would the answer be -5, -2, 2, 4??
The answer to this question is D! Thank you Steve

The expression n(n-1)-5 represents the sequence. We can plug in values for n to find the first four terms of the sequence.
When n=1, we get 1(1-1)-5 = -5
When n=2, we get 2(2-1)-5 = -3
When n=3, we get 3(3-1)-5 = 1
When n=4, we get 4(4-1)-5 = 7
The first four terms of the sequence are -5, -3, 1, and 7.
Given the function rule `f(x) = x² - 3x + 2`, we can find the output of `f(-2)` by substituting `-2` for every `x` in the expression for `f(x)` and simplifying:
f(-2) = (-2)² - 3(-2) + 2
= 4 + 6 + 2
= 12
Therefore, the output of `f(-2)` is `12`.
your the best
@kid are you sure
So, you can just plug the number in! Just use your simple knowledge on PEMDAS
what are the first four terms of the sequence represented by the expression n(n-1)-5?
Given the function rule f(x) = x²-3x+2, what is the output of f(-2)?
Suppose you earn $10 each hour you babysit. Which function describes the relationship
between your total earnings E and the number of hours you babysit, h?
To find the function that describes the relationship between your total earnings E and the number of hours you babysit, h, we need to recognize that your total earnings are equal to your hourly rate "r" multiplied by the number of hours you work "h".
Accordingly, in this scenario we have:
- Your hourly rate, r = $10 per hour
- The number of hours you babysit, h is a variable
So, our function that represents the relationship between the number of hours and the total earnings is:
`E(h) = r * h`
Substituting the value of "r", we get:
`E(h) = 10h`
Therefore, the function that describes the relationship between your total earnings E and the number of hours you babysit, h is `E(h) = 10h`.
Max charges $3.50 per hour when he mows lawns, plus $6.00 for transportation expenses. Which function rule represents the amount y Max charges to mow lawns for x hours?
Max charges $3.50 per hour when he mows lawns, plus $6.00 for transportation expenses.
The function rule `y` that represents the amount Max charges to mow lawns for `x` hours is:
`y = 3.50x + 6.00`
In this equation, `y` represents the total fee Max charges for the given number of hours of mowing, `x`. The term `3.50x` represents the amount Max charges per hour and `6.00` represents the transportation expenses.
Therefore, the function rule representing the amount `y` Max charges to mow lawns for `x` hours is `y = 3.50x + 6.00`.
The sale price of ground beef at a local grocery store is $1.49 for the first pound and $1.09 for each additional pound. Which function rule shows how the cost of ground beef, y, depends on the number of pounds, x?
The sale price of ground beef at a local grocery store is $1.49 for the first pound and $1.09 for each additional pound. This is equivalent to saying that the first pound costs $1.49 and each additional pound beyond the first costs $1.09.
So, if we let `y` represent the total cost of `x` pounds of ground beef, then we can represent this relationship with the following function rule:
```
y = 1.49 + 1.09(x - 1)
```
In this equation, the term `1.49` represents the cost of the first pound and the term `1.09(x - 1)` represents the cost of the remaining `(x - 1)` pounds.
Therefore, the function rule that shows how the cost of ground beef, `y`, depends on the number of pounds, `x`, is `y = 1.49 + 1.09(x - 1)`.
how do you write a function rule?
A function rule is a specific expression that represents the relationship between two or more variables. There is no one-step method for writing a function rule, but you can follow these general steps:
1. Understand the problem: Understand what the problem is asking for and identify the input (the independent variable) and the output (the dependent variable).
2. Determine the type of relationship: Determine what type of equation/model would represent the relationship between the input and output variables. For example, is the relationship linear, quadratic, exponential, or something else? You can use the context of the problem to help you determine this.
3. Identify the equation form: Write the equation or formula that represents the relationship between the input and output variables in the correct form. For example, a linear equation is written in the form y = mx + b, where m is the slope and b is the y-intercept.
4. Replace variables with labels: Replace the variables in the equation with the corresponding variable names or labels that are used in the problem.
5. Check your work: Check your work to make sure that the equation accurately represents the problem and that the correct units are included.
Overall, writing a function rule requires careful analysis of the problem at hand and the application of mathematical formulas and equations.
Explain how to write a function rule from the table below. Then write a function rule.
To write a function rule from a table, we need to examine the relationship between the input values (usually the values in the first column) and the output values (usually the values in the second column). Once we identify the relationship, we can write a function rule that represents this relationship. Here are the steps to follow:
1. Determine the type of relationship: Look for a pattern or trend in the table to help determine the type of relationship between the input and output values. For example, the relationship may be linear, quadratic, or exponential.
2. Write the general form of the equation: Based on the type of relationship, write the general form of the equation that will represent the relationship between the input and output values.
3. Find the specific values: Plug in the specific input and output values from the table to find the constants or coefficients needed for the specific function rule.
Here's an example:
Suppose we are given the following table:
| x | y |
|---|---|
| 1 | 5 |
| 2 | 7 |
| 3 | 9 |
| 4 | 11 |
1. From the table, we can see that there is a linear relationship between `x` and `y`. Specifically, as `x` increases by 1, `y` increases by 2.
2. The general form of a linear equation is `y = mx + b`, where `m` is the slope of the line and `b` is the y-intercept.
3. We can find the specific values for `m` and `b` by using any two data points in the table. For example, let's use the first two data points `(1, 5)` and `(2, 7)`.
- Slope `m` = (y2 - y1) / (x2 - x1) = (7 - 5) / (2 - 1) = 2
- y- intercept `b` = y - mx = 5 - (2)(1) = 3
4. Putting it all together, we can write the function rule, which represents the relationship between `x` and `y` as:
`y = 2x + 3`
Therefore, the function rule that fits the table is `y=2x+3`.
Explain how to write a function rule from the table below. Then write a function rule.
X

210-1
y
The table given to us looks incomplete as there is no value for y corresponding to the input value of 4 and 6. However, for the input value x = 0, we have an output value of y = 2, and for the input value of x = 10, we have an output value of y = 9.
Based on the table, we see that there is no fixed pattern or trend between x and y. It means that the relationship between x and y can be non-linear and complex. We may use various techniques and heuristics to find a function rule that approximates the data "points" in the table.
One thing we can do is to calculate the difference between each pair of consecutive y values as the input increases by 1. We can see that the differences are not constant, which indicates that there may not be a simple formula connecting x and y. Alternatively, we may graph the points and try to "eyeball" the most natural curve passing through them, or we may use regression analysis or interpolation techniques to find a function rule.
Without additional information or constraints, it is difficult to identify a single function rule that uniquely represents the given table.

how can i sound like i have an Australian accent?
To sound like you have an Australian accent, you can try the following tips:
1. Use a relaxed tone: Australian accents are known for being relaxed and drawling. Speak slowly and leisurely, rather than in a hurried or rushed manner.
2. Flatten your vowels: Australians tend to flatten their vowels, so try elongating them a little more. For example, instead of saying "mate," say "maet" and instead of "mate," say "maight."
3. Use the "a" sound: Australians often use the "ah" sound more than the "o" sound. For example, "rock" may sound more like "rack."
4. Pronounce "r" sounds: Unlike in British accents, Australians tend to pronounce the "r" sound at the end of words, as well as the beginning of words that start with "r."
5. Use Australian slang: Incorporate some common Australian slang into your speech to sound more authentic.
Remember that accents can be difficult to master, so don't be discouraged if it takes some practice to sound the way you want.
how about scottish?
To develop a Scottish accent, you can try the following tips:
1. Listen to Scottish people speaking: One of the best ways to develop an accent is to listen to native speakers. Try watching Scottish TV shows or movies, or listening to Scottish music and podcasts.
2. Emphasize your "R's": Scottish accents tend to put a lot of emphasis on "R's", especially at the end of a word or before a consonant. You can try to roll your "R's" slightly, or to make the sound more guttural.
3. Use Scottish slang: Incorporate some common Scottish slang into your speech to sound more authentic.
4. Use elongated vowels: Scottish speakers can elongate their vowel sounds, particularly the "o" sound, for example making "boat" sound more like "boaut".
5. Practice Emphasis on the second syllable of certain words: Scottish people tend to emphasise the second syllable of certain words, for instance making "com-PUT-er" sound like "COM-pyoo-tah".
Remember, accents can be difficult to master, so don't be discouraged if it takes some practice to get it right!
how about mexican?
To develop a Mexican accent, you can try the following tips:
1. Listen to native Spanish speakers: The majority of people in Mexico speak Spanish, so you can listen to Spanish-language music, watch TV shows or movies that feature Mexican speakers, or talk to a Mexican friend to get an idea of how the accent sounds.
2. Practice the trilled "R" sound: In Spanish, the "R" sound is rolled or trilled. Try to learn how to roll your tongue and pronounce "R" sounds with a trill to match the accent.
3. Emphasize the "E" and "O" vowels: In Mexican Spanish, the "E" and "O" vowels are emphasized, and elongated. Instead of saying "no," say it more like "no-o" or "yes" as "Sii-i".
4. Use common Mexican Spanish expressions: Incorporate common Mexican Spanish expressions or phrases used commonly into your speech to sound more authentic.
5. Practice making a difference between 'L' and 'Y' sounds: Mexican Spanish makes a clear difference between the 'L' and 'Y' sounds. For example, palabras (words) sound more like "pa-LA-brahs" with emphasis on the 'LA' in the middle.
Remember that accents can be difficult to master, so it's important to be patient and practice on a regular basis to develop a natural-sounding accent.

what are the first four terms of the sequence represented by
the expression n(n-1)-4
#1 -2,2,6,10
#2 -3,0,3,6
#3 -4,-2,2,8
#4 -5,-4,-2,6
The expression `n(n - 1) - 4` represents a sequence. To find the first four terms of this sequence, substitute the first four positive integers (1, 2, 3, and 4) into the expression and simplify. Here are the results:
- When n = 1, `n(n - 1) - 4` = `1(1 - 1) - 4` = `-4`
- When n = 2, `n(n - 1) - 4` = `2(2 - 1) - 4` = `-2`
- When n = 3, `n(n - 1) - 4` = `3(3 - 1) - 4` = `2`
- When n = 4, `n(n - 1) - 4` = `4(4 - 1) - 4` = `8`
