Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x
g(x) = 4x + 5
<u>Step 2: Find</u>
- Substitute in functions: 2x + 3(4x + 5)
- [Distributive Property] Distribute 3: 2x + 12x + 15
- Combine like terms: 14x + 15
Knowing that one mile is 5,280 feet and an hour is 60 minutes:
10 x 5280 = 52800
60 x 1 = 60
52800 / 60 = <u><em>880 feet per minute</em></u>
Hope this helps!
