help_people one year ago 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

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

4. Nnesha

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

5. Nnesha

$\huge\rm \color{reD}{f(x)}+\color{blue}{g(x)}$ 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

6. help_people

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

7. Nnesha

how did you get -15 ?

8. help_people

k here is my work: 4x + -13 + 10x + -2 4x+ -13 + 10x + -2 = (4x + 10x) + ( -13 + -2) = 14x + -15 Answer is : 14x -15

9. Nnesha

it's not -13 13 is positive

10. help_people

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

11. Nnesha

you don't need a calculator for this one and i'm pretty sure u pluggedin wrong thing

12. help_people

you did ask 4x - 13 so it actually is negative i am not trying to debate with you but i am jus trying to make sure that we are on the same page lol

13. Nnesha

nvm i typed it wrong

14. Nnesha

well it's 4x+13 in the question i'm stupid but you should pay attention :=)

16. help_people

ok lol well i will do that now : D

17. help_people

14x+11 i believe @Nnesha

18. Nnesha

right
