Question

What is the value of the function y=1 over 8x−13 when x=−4 ?(1 point)
Responses

A.−15

B.−13.5

C.−12.5

D.−16

Answer 1

choose the correct answer

Answer 2

which one is closest to the answer

Answer 3

To find the value of the function when x = -4, we substitute -4 into the function:

y = 1/(8x - 13)
y = 1/(8(-4) - 13)
y = 1/(-32 - 13)
y = 1/(-45)
y = -1/45

Thus, the value of the function y = 1/(8x -13) when x = -4 is -1/45.

Therefore, option D. -16 is not the correct answer.

Answer 4

Apologies for the mistake in the previous response. Let's calculate the correct answer:

Given the function y = 1/(8x - 13), we substitute x = -4 into the function:

y = 1/(8(-4) - 13)
y = 1/(-32 - 13)
y = 1/(-45)
y = -1/45

So, the correct answer is not listed. None of the given options A, B, C, or D are correct.

Answer 5

Apologies for the confusion. To find the value of the function y = 1/(8x - 13) when x = -4, we substitute -4 into the function:

y = 1/(8(-4) - 13)
y = 1/(-32 - 13)
y = 1/(-45)
y ≈ -0.0222

Since none of the given options (-15, -13.5, -12.5, -16) are close to -0.0222, none of them is the correct answer.
