Question

If f(x)=-2x+9, then find the value of the x value that makes F(x)=-22

Answer 1

To solve for the value of x where f(x) = -22 for the function f(x) = -2x + 9, we set up the equation -2x + 9 = -22, subtract 9 from both sides, and then divide by -2, resulting in x = 15.5.

Step-by-step explanation:

To find the value of x that makes f(x) = -2x + 9 equal to -22, we need to set the function equal to -22 and solve for x.

-2x + 9 = -22

First, subtract 9 from both sides:

-2x = -22 - 9

-2x = -31

Next, divide both sides by -2 to solve for x:

x = 31 / 2

x = 15.5

The value of x that makes f(x) equal to -22 is 15.5.

Answer 2

-22 = -2x + 9
-31 = -2x
-31/-2 = x
x = 15.5
