General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(4x² - 2x - 3) + (-3x² + x + 7)
<u>Step 2: Simplify</u>
- Combine like terms (x²): x² - 2x - 3 + x + 7
- Combine like terms (x): x² - x - 3 + 7
- Combine like terms (Z): x² - x + 4
The equation is y= -2x + 1
Equation: y=x-2 , Hope this helps!
10x-9=9x
-9=-x
x=9
angle 7 = 9*(9)=81
angle 6 = 180-81= 99
