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.
Have you understood ?

Explanation:
We need to find two points that are solutions to the equation.
So, if x = 0, then:
y = -3x - 4
y = -3(0) - 4
y = 0 - 4
y = -4
And, if x = 1, then:
y = -3(1) - 4
y = -3 - 4
y = -7
Answer:
Then, the line passes through the points (0, -4) and (1, -7). So the graph of the equation is:
Step-by-step explanation:
y + 4 = -4(x - 2) = -4x + 8
y - 4 = -4x
-4x - y = -4
4x + y = 4
The first twin. The lucky numbers must be 2 and 1, respectively. The second twin is lying because 2+(1x2)= 4 not 5.
