Answer: It would be d,15m
Hi,
f + g is a simple sum of the functions. This refers to increasing the good effect of exercise with diet effect, therefore more weight could be lost.
(f + g)(x) = f(x) + g(x) = 2x + 210 + 2x + 125 = 4x + 335, so (f + g)(x) = 4x + 335.
For x = 3 (meaning 3 hours of exercise) we have:
(f + g)(3) = 4·3 + 335 = 12 + 335 = 347 calories, after 3 hours of exercice.
The correct answer is: 347 calories burned while combining diet with 3 hours of exercise.

Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point form: (3, -3)
Equation form: x = 3, y= -3
to get the slope of a line all we need is two points off of it, so let's get two points from that table
