Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 1 - x
g(x) = x² + 2x - 5
(f + g)(x) is f(x) + g(x)
<u>Step 2: Solve</u>
- Substitute in functions: (f + g)(x) = (1 - x) + (x² + 2x - 5)
- Combine like terms (x): (f + g)(x) = x² + x - 5 + 1
- Combine like terms: (f + g)(x) = x² + x - 4
Answer:
Mass determines how fast a car can accelerate. Since a car accelerates slower with more adults, and faster with less adults, this means that the mass has a big impact on acceleration. Therefore, we can conclude that the mass determines how fast a car can accelerate.
Answer: 20 Miles
Step-by-step explanation:
19 miles north and then 3 miles south is just 16 miles north.
16 miles west and then 4 miles east is just 12 miles west.
√16^2+12^2 = √256 + 144
√256+144 = √400
√400 = 20
The traveler is 20 miles from the original starting point.
(I honestly don't know why you'd use this formula, but it's what I was taught.)
