Answer:
The roots of the given equation are x = 0 and x = -8.
General Formulas and Concepts:
<u>Algebra I</u>
Terms/Coefficients
Quadratic Equations
- Solving quadratic equations
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
y = x² + 8x
<u>Step 2: Find Roots</u>
- [Quadratic] Factor: y = x(x + 8)
- [Quadratic] Set up [Solve]: 0 = x(x + 8)
- [Quadratic] Define: x = 0, -8
∴ the roots of the quadratic equation y = x² + 8x is equal to 0 and -8.

Topic: Algebra I
Answer:
(-2,-3)
Step-by-step explanation:
For a counterclockwise rotation of 180° about the origin,(x,y)–(-x,-y)
Therefore
(2,3)–(-2,-3)
Answer:
(6,1)
Step-by-step explanation:
You know that to move up or down means to change the y- coordinate. So for this on you do 10-9. This is 1. So the new y- coordinate is 1.
