Question

The function f(x) = 2x + 210 represents the number of calories burned when exercising, where x is the number of hours spent exercising.

The function g(x) = 2x + 125 represents the calorie deficit that occurs when following a particular diet, where x is the number of hours spent exercising.

What is (f + g)(2)? Explain.

214 calories burned while exercising for 2 hours.
214 calorie calories burned when combining diet with 2 hours of exercise.
343 calories burned while dieting for 2 hours.
343 calories burned while combining diet with 2 hours of exercise.

Answer 1

All we need to do is solve for (f + g)(2) because we already know that f(x) = 2x + 210 represents the number of calories burned when exercising and g(x) = 2x + 125 represents the calorie deficit that occurs when following a particular diet

Answer 2

?

Answer 3

Wait actually

Answer 4

But that isn't an answer... ?? I am sorry. I am dumbb

Answer 5

No you don't have to say that

Answer 6

Answer 10

He said D

Answer 11

Oof I am trying to put it into the equation thing and I just solved it but its not working

Answer 12

okey new question

Answer 13

f+g=2x+210+2x+125\\\\f+g=4x+335\\\\(f+g)(2)=4\times 2+335\\\\(f+g)(2)=8+335=343

Answer 14

This is what I am trying to do

Answer 15

mchen said it's D

Answer 16

Hes right

Answer 17

\[f+g = 2x+210\]
