Answer:
6x + y = -40
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Distributive Property
- Equality Properties
<u>Algebra I</u>
Standard Form: Ax + By = C
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
[Point Slope] y + 4 = -6(x + 6)
<u>Step 2: Rewrite</u>
<em>Find standard form</em>
- Distribute -6: y + 4 = -6x - 36
- Add 6x on both sides: 6x + y + 4 = -36
- Subtract 4 on both sides: 6x + y = -40
Answer: 15x² + 2x + 4
x = -2/3, 0, 1/2
Step-by-step explanation:
5x(3x + 2) - 4(2x - 1)
First, distribute:
15x² + 10x - 8x + 4
Combine like terms:
15x² + 2x + 4
This is your polynomial!
If you needed to solve for x, take your original factored polynomial and set each term equal to 0:
5x(3x + 2) - 4(2x - 1)
5x = 0
x = 0
3x + 2 = 0
3x = -2
x = -2/3
-4 = 0
No solution
2x - 1 = 0
2x = 1
x = 1/2
x = -2/3, 0, 1/2

Answer:
J&L M&N
Step-by-step explanation:
These pairs of rectangles are similar because they all have fours sides, the horizontal lines are longer than the parallel lines, and they are all parallelograms
