Respuesta :

(f+g)(3) = f(3) + g(3) = 6(3) + 3 + 3 -7 = 18 +6 -7 = 17.

Answer: 17

Answer:

Option B is correct

[tex](f+g)(3)[/tex] = 17

Step-by-step explanation:

Given the functions:

f(x) = 6x+3

g(x) = x-7

Solve: [tex](f+g)(3)[/tex]

First do:

[tex](f+g)(x) = f(x)+g(x)[/tex]

Substitute the given values we have;

[tex](f+g)(x) = 6x+3+x-7 = 7x-4[/tex]

Put x = 3 above we have;

[tex](f+g)(3) = 7(3)-4 = 21-4=17[/tex]

Therefore, the value of [tex](f+g)(3)[/tex] is 17
