Question

The point (z,-8) is an ordered pair of the function f(x)= 1/2x-2.

What is the value of x?
A. = -6
B. = -12
c.= -3
D. =-18

Answer 1

The value of x in the function f(x)= 1/2x-2 for the point (z,-8) is -12.

Step-by-step explanation:

The point (z,-8) represents an ordered pair on the function f(x)= 1/2x-2. To find the value of x, we can substitute the given y-coordinate of -8 and solve for x:

-8 = 1/2x-2

Adding 2 to both sides, we get:

-6 = 1/2x

Multiplying both sides by 2, we get:

-12 = x

Therefore, the value of x is -12. So, the answer is B. = -12.
