What is the value of the function y=1/8x−13 when x=−4?

Answer 1

To find the value of the function, we substitute x = -4 into the equation y = (1/8)x - 13:

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

y = -1/2 - 13

y = -1/2 - 26/2

y = -27/2

Therefore, when x = -4, the value of the function is -27/2.

Answer 2

What is the value of the function y=18x−13 when x=−4?
−13.5 −15 −16 −12.5

Answer 3

To find the value of the function, we substitute x = -4 into the equation y = 18x - 13:

y = 18(-4) - 13

y = -72 - 13

y = -85

Therefore, when x = -4, the value of the function is -85.

Answer 4

wrong

Answer 5

Apologies for the mistake. Let's calculate the value of the function correctly this time.

When x = -4, we substitute this value into the equation y = 18x - 13:

y = 18(-4) - 13

y = -72 - 13

y = -85

Therefore, when x = -4, the value of the function y = 18x - 13 is -85.
