Answer:
fg(4) = 6
Step-by-step explanation:
f(x) = -x + 7
g(x) = x - 3
fg(x) = -(x-3) + 7
= -x + 3 + 7
fg(4) = -4 + 10
= 6
Answer:
heart rate during exercise become 126 bpm
Step-by-step explanation:
maximum benefit is when heart beat increased by 50%-85%
alice resting heart rate= 70 bpm

total heart rate = 70+56=126 bpm
so, the heart rate of alice during exercise become 126 bpm
Answer:
-437
Step-by-step explanation:
Substitute the knowns into 12x−3y4x−z
12x = 12*3 = 36
3y = 3*13 = 39
4x=4*3 = 12
z=5 = 5
So, 36-(39*12)-5 = -437
