Answer 1

[AI-generated answer — Bot GPT 3.5]

The value of the function y = 1/8x - 13 when x = -4 is -15.

Plugging in x = -4 into the equation gives:
y = 1/8(-4) - 13
y = -1/2 - 13
y = -15

Therefore, the value of the function when x = -4 is -15.

Answer 3

[AI-generated answer — Bot GPT 3.5]

To find an ordered pair (x, y) that is part of the relation y = -23x + 6, we can substitute the given x-values into the equation to determine the corresponding y-values.

1. For the pair (0, -23):
When x = 0,
y = -23(0) + 6
y = 0 + 6
y = 6, not -23.
So, (0, 6) is not a part of the relation.

2. For the pair (3, 4):
When x = 3,
y = -23(3) + 6
y = -69 + 6
y = -63, not 4.
So, (3, -63) is not a part of the relation.

3. For the pair (3, 8):
When x = 3,
y = -23(3) + 6
y = -69 + 6
y = -63, not 8.
So, (3, -63) is not a part of the relation.

4. For the pair (1, 4):
When x = 1,
y = -23(1) + 6
y = -23 + 6
y = -17
So, (1, -17) is not a part of the relation.

None of the given pairs are part of the relation y = -23x + 6.

Answer 4

Oh sorry It's the equation is: y=−2/3x+6 ?

Let's find the ordered pair that is part of the relation y = -2/3x + 6.

Given relation: y = -2/3x + 6

Substitute the x-values in the ordered pairs to see which one corresponds to the relation:

1. For the pair (0, -23):
When x = 0:
y = -2/3(0) + 6
y = 0 + 6
y = 6

So, (0, 6) is part of the relation.

2. For the pair (3, 4):
When x = 3:
y = -2/3(3) + 6
y = -2 + 6
y = 4

So, (3, 4) is part of the relation.

3. For the pair (3, 8):
When x = 3:
y = -2/3(3) + 6
y = -2 + 6
y = 4

So, (3, 4) is part of the relation.

4. For the pair (1, 4):
When x = 1:
y = -2/3(1) + 6
y = -2/3 + 6
y = 4

So, (1, 4) is part of the relation.

Therefore, the ordered pair that is part of the relation y = -2/3x + 6 is (0, 6).

Answer 6

Identify which of the following functions is proportional.(1 point)

Responses

y=1/2x
y equals Start Fraction 1 over 2 End Fraction x

y=x+1/2
y equals x plus Start Fraction 1 over 2 End Fraction

y=x^2
y equals x squared

y=1/2x

Answer 7

[AI-generated answer — Bot GPT 3.5]

A function is proportional if it is in the form of y = kx, where k is a constant. Let's analyze each of the provided functions:

1. y = 1/2x
This function is proportional because it is in the form y = kx where k = 1/2. Thus, this function is proportional.

2. y = x + 1/2
This function is not proportional because it includes an additional constant term (1/2) that is not directly proportional to x.

3. y = x^2
This function is not proportional because it includes an x squared term, indicating a non-linear relationship between x and y.

4. y = 1/2x
This is the same function as provided in option 1. We have already established that y = 1/2x is proportional because it is in the form y = kx where k = 1/2.

Therefore, the function that is proportional is y = 1/2x.

The correct answer should be written as:

y = (1/2)x

The equation represents a proportional relationship between y and x, where y is equal to half of x.
