What is the value of the function y=18x−13 when x=−4?

sry, i meant y=1/8x−13

No problem!

When x=-4, we can substitute the value of x in the equation to get:

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

Simplifying this, we get

y = (-1/2) - 13

y = -13.5

Therefore, the value of the function y = (1/8)x - 13 when x = -4 is -13.5.

To find the value of the function y = 18x - 13 when x = -4, you need to substitute -4 in place of x in the equation and evaluate it.

Substitute -4 for x in the equation y = 18x - 13:

y = 18(-4) - 13

Now, simplify the equation:

y = -72 - 13

Combine like terms:

y = -85

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

When x=-4, y=18(-4)-13 = -85.

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