Chapter One

100

What is the property: (4 x 7)m = 7(4m), represents? 

The Associative Property

200

Solve 8/√6 rounded to the nearest tenth.

3.3

300

Simplify:  8m + 4(2m - 7)

16m - 28

400

Solve f(m) =  23 + .37m Where m is equal to 2, -3, and 10, rounded to the nearest hundredth.

m(2) = 23.74

m (-3) = 21.89

m(10) = 26.7

500

Write 13⁶ = 58 in logarithmic form.

log₁₃58 = 6

Chapter Two

100

Solve: 12m = 6(3m -14)

m = 14

200

What are the x and y intercepts of 3y + 7x = 21?

x = 3

y = 7

300

Solve: |m + 12| = 5

m = -7, -17

400

What is the slope of a line that passes through 

(-15, 70) and (5, 10)?

-3

500

Evaluate: log₉81

log₉81 = 2

Chapter Three

100

Solve for x and y: 

y = 4x 

y - x = 12

x = 4 y = 16

200

Solve for x and y:

15x - y = 33

21x + y = 51

x = 7/3

y = 2

300

Solve for x, y, and z:

3x + 2y + 7z = 22

5z - 2x +y = -6

-y - 10z + 4x = 24

x = 4

y = 12

z = -2

400

Solve for x, y, and z:

3x + 4y + z = 48

2x + 7y - 9z = -15

-2z - 5x + 10y = 34

x = 4

y = 7

z = 8

500

Express as a single logarithm and simplify:

log₂2 + log₂16

log₂32 = 5

Chapter Five

100

Find the Roots: x² + 5x − 24

x = 3

x = -8

200

What is the quadratic function in standard form for the set of zeros: -7 and 12

x² − 5x − 84

300

Solve by Completing the Square x² + 4x = 6

x = -2 ±√10

400

Solve Using the Quadratic Formula: x² - 6x + 12

x = 3 ± i√3

500

Solve 5^x+8 = 1/3

x = −8.683

Chapter Six

100

Add, write your answer in standard form. 

(4x - 8x² + 13) + (12x² -x)

4x²  + 3x + 13

200

Subtract, write your answer in standard form.

(13 + 9x² - 18x) - (-2x² + 23x)

11x² − 41x + 13

300

Find the Product:

(x+14)(20 + 3x - 7x²)

−7x³ − 95x² + 62x + 280

400

Divide: (2x⁴ - 6x² + 17x - 10) / (x - 2)

2x³ + 4x² + 2x + 21 + 32/x-2

500
