General Formulas and Concepts:
<u>Algebra I</u>
- Composite Functions
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x² + 1
g(x) = x² - 5
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find (f + g)(x)</u>
- Substitute: (f + g)(x) = 4x² + 1 + x² - 5
- Combine like terms: (f + g)(x) = 5x² - 4
Answer:
x = 1
Step-by-step explanation:
4x + 6 - x = 7 + 2x
3x + 6 = 7 + 2x
3x - 2x = 7 - 6
x = 1
4/5*3/7=a
a=12/35
