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:
2 and 4
Step-by-step explanation:
1% of 72 is 0.72
0.72 * 40
is 28.8
10% of 72 is 7.2
7.2 * 4 is also 28.8
40% of 70 is 28.8
