Answer:
g(f(x)) = x² + 6x + 9
General Formulas and Concepts:
<u>Algebra I</u>
- Composite Functions
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² + 6x + 7
g(x) = x + 2
g(f(x)) is x = f(x)
<u>Step 2: Find g(f(x))</u>
- Substitute: g(f(x)) = (x² + 6x + 7) + 2
- Combine like terms: g(f(x)) = x² + 6x + 9
I’m not 100% sure but I’d say B
45 new houses...
1/3 were sold......1/3(45) = 45/3 = 15 houses sold.....leaving 45 - 15 = 30 houses left. 1/5 of remaining houses sold....1/5(30) = 30/5 = 6...so 6 more houses were sold.....leaving 30 - 6 = 24 houses
24 houses are left <==
The answer would be
X = 6 - y / 2 !
