When following the slope formula, its the y values on top, in this ,
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.

Answer:
74893 students per year
Step-by-step explanation:
The Average rate of change is calculated as
= Difference in number of students / Difference in years
= 3120 thousand - 5217 thousands/ 2008 - 1980
= (3120000 - 5217000)/(2008 - 1980)
= -2097000/28
= -74892.857143 per year
Therefore, the average rate of change
per year in the number of high school dropouts is approximately 74893 students per year
