Multi-Step / Literal Equations

100

Solve for x:

4 = -2(x+3)

x = -5

200

y = mx + b, solve for b

b = y - mx

300

Solve for a:

(1/3)a + 2 = 9

a = 21

400

P = (R - C) / N, solve for R

R = PN + C

500

A = p(1 + rt), solve for t

t = [(A / p) - 1] / r

Linear Equations / Inequalities

100

What is the formula to calculate the slope of a line?

m = (y2 - y1) / (x2 - x1)

200

Tell whether the 2 lines are parallel, perpendicular, or neither:

1) y = (2/3)x + 7

2) y = (-3/2)x + 8

Perpendicular (slopes are opposite reciprocals)

300

Solve the inequality:

50 < 8 - 6x

x < -7

400

Solve the compound inequality:

-50 < 7x + 6 < -8

Answer 1)  -8 < x < -2

Answer 2)  x > -8 AND x < -2

500

Write the equation of a line that is parallel to y = (7/5)x + 4, and goes through the coordinate point (5, 2). Please write in slope-intercept form.

y = (7/5)x - 5

Polynomials / Exponents

100

Subtract the following polynomials:

(3x³ - 6x + 10) - (2x² - 6x + 7)

3x³ - 2x² + 3

200

Simplify:

(7a²b³c⁴) x (3a²b³c⁴) x (4abc)

84a⁵b⁷c⁹

(Ken Jennings - Jeopardy's winningest contestant)

400

Simplify:

(2x + 8y) (6x - 10y)

12x² + 28xy - 80y²

500

Simplify:

[(20x^3) / (7y^-2)] ^2

(400x⁶y⁴) / 49

Factoring

100

Find the GCF:

18x⁵ + 36x³ - 48x⁴

6x³

300

Factor completely:

15x³ - 45x² + 105x

15x (x² - 3x + 7)

400

Factor the following:

x² - 18x - 40

(x - 20) (x + 2)

500

Factor the following:

(3x² + 17x + 24)
