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

OpenStudy (freckles):

plug in 5 into both

OpenStudy (freckles):

then add the results

OpenStudy (arindameducationusc):

I agree with @freckles

OpenStudy (arindameducationusc):

32-(-4)

OpenStudy (anonymous):

36

OpenStudy (arindameducationusc):

yup...

OpenStudy (anonymous):

thats not the answer right

OpenStudy (freckles):

did you input 5 into both functions @maria12vera ? what is 8(5)-13?

OpenStudy (arindameducationusc):

oops its 40-13=27

OpenStudy (arindameducationusc):

so, 27-(-4)

OpenStudy (arindameducationusc):

so, now 100% answer should come

OpenStudy (freckles):

(f+g)(5) f(5)+g(5) (8*5-13)+(5-9) compute this to get the answer

OpenStudy (freckles):

@arindameducationusc you change the addition to subtraction

OpenStudy (arindameducationusc):

Nice steps @freckles Ya, Thats the way

thanks @arindameducationusc and @freckles
