Question

Given f(x) = 4x + 13 and g(x) = 10x − 2, solve for (f + g)(x) and select the correct answer below.

(f + g)(x) = 14x + 15
(f + g)(x) = 14x + 11
(f + g)(x) = 6x + 11
(f + g)(x) = 6x + 15

Answer 1

@Vocaloid

Answer 2

add both function f(x)+g(x)

Answer 3

how would i do that just add f(x) + f(x)

Answer 4

f(x) and g(x)
what is f(x) equal to ? and what is g(x) equal to ?

Answer 5

\[\huge\rm \color{reD}{f(x)}+\color{blue}{g(x)}\]
f(x) =4x+13
g(x)=10x-2
so replace f(x) and g(x) for 4x+13 and 10x-2 \[\huge\rm \color{reD}{(4x-13)}+\color{blue}{(10x-2)}\]
combine like terms

Answer 6

14x-15 @Nnesha sorry internet connection hapned :/

Answer 7

how did you get -15 ?

Answer 8

k here is my work:

4x + -13 + 10x + -2

4x+ -13 + 10x + -2

= (4x + 10x) + ( -13 + -2)

= 14x + -15

Answer is : 14x -15

Answer 9

it's not -13
13 is positive

Answer 10

I'm not sure i have a math website that a trust and 14x-15 came up with it its called mathway
