Is(0,3) a solution to the equation y=x+3
A. Yes
B. No***
Is (1,4) a solution to the equation y= -2x
A. Yes***
B. No
Look at the following points
(4,0) (3,1) (6,3) (2,-4)
Which are the solutions to y= x-4? Choose all the correct answers
A.(6,3)
B.(4,0)***
C.(3,-1)
D.(2,-4)***
If you are in connexus here are all of the answers.
1 yes
2 no
3 (4,0) & (3,-1)
4 96
5 3y+6=5y-8
6. An equation can be used to predict values from a pattern by merely substituting any value to determine the equivalent value. An example is the geometric series which has a standard equation of an = a1 * r^(n-1) and is used to predict the nth term of the series
7 Price # of pizzas
1.)50 1
3.)00 2
4.)50 3
6.)00 4
each pizza costs 1.50 so you add on 1.50 to each slice of pizza you buy
just took the test got 100%
1.A
2.B
3.B,C
4.B
How are you doing these ??
#1 , (0,3) a sollution to y = x+3
Left Side = y = 3
Right Side = x+3 = 0+3 = 3
LS = RS
So, YES, (0,3) lies on y = x+3
#2 (1,4) a solution to y = -2x ??
LS = 4
RS = -2(1) = -2 ≠ 4
So NO
#3
y = x-4
for (6,3) ---> is 3 = 6-4 , NO
for (4,0) ---> is 0 = 4-4, YES, Yeahhh, first one right!
for (3,-1) --> is -1 = 3-4 , YES
for (2,-4) --> is -4 = 2-4 , NO
You got 1 correct out of 6.
Somebody has some serious work ahead.
2020 gangg is right got 100%
Can confirm, it is almost the end of 202, and 2020 gangg is right

5. An example would be x+4 = 8
6. Using equations, you will are able to predict data from a specific value of independent variable. You can see how does the independent variable affect the dependent variable.
7. The y is the cost of the pizza when you buy x slices at 1.50 per slice. So the equation in y = mx + b form is y = 1.5x
