Question

Solve f(x) = 2x + 2 what would f(x)=20a. 20b. 10c. 9d. 8​

Answer 1

Answer:

C

Step-by-step explanation:

Given f(x) = 2x + 2 and f(x) = 20, then equate right sides, that is

2x + 2 = 20 ( subtract 2 from both sides )

2x = 18 ( divide both sides by 2 )

x = 9 → C

Answer 2

Answer:

the answer is c. 9

Step-by-step explanation:

20=2x+2

18=2x

x=9
