Question

given the following functions f(x) and g(x), solve (f + g)(5) and select the correct answer below: f(x)=8x - 13 g(x)=x - 9 23 40 27 31

Explanation:

Step1: Find (f + g)(x)

(f + g)(x)=f(x)+g(x)=(8x - 13)+(x - 9)=9x-22

Step2: Substitute x = 5

(f + g)(5)=9\times5-22
(f + g)(5)=45 - 22=23

Answer:

23
