This lesson contains the answer keys for the following lessons: Matrices & Absolute Values: Homeschool Assignments; Exponents & Polynomials: Homeschool Assignment; Factoring, Graphing Parabolas & Solving Quadratics: Homeschool Assignments. Updated: 08/05/2020

Note: all steps and solutions should be documented in student work.

Matrices & Absolute Value Answer Key

1. 11

2. 38

3. x = 3, -10

4. x = 5, 1

5. (-7,0)

6. y = |x - 3| - 4

7. y = 4 |x - 4| + 1

8.

absolute value graph for y = |x - 2|

9.

absolute value graph for y = |x + 1| - 2

Exponents & Polynomials Answer Key

1. 3ab3c2

2. x3/125

3. 3pq4/3

4. The graph is either cubic or quintic. We know that graphs will a positive leading coefficient and odd exponents go down to infinity at the left and up to infinity at the right.

5. 4x4 - 3x3 - 3x2 - 2x + 4

6. 3x2 - 4x + 8

7. -2x4 + 2x3 - 8x2 + 4x - 1 + 3 / (x + 4)

8. First you need to isolate z by performing operations on both sides of the equals sign: z = 2y - 3x

Then substitute the given values for y and x: z = 2*3 - 3*1
