Question

Given the function ƒ(x) = 8(x - 4) - 18, determine the value of x such that ƒ(x) = 22. Select one: A. 3 B. 6 C. 9 D. 12

Answer 1

Answer:

C). 9

Step-by-step explanation:

Given: f(x) = 8(x - 4) - 18

If f(x) = 22;

8(x - 4) - 18 = 22

8x - 32 - 18 = 22

8x - 50 = 22

8x = 22 + 50 = 72

x = 72 ÷ 8 = 9
