Review #1

SOLVING LINEAR EQUATIONS, INEQUALITIES AND ABSOLUTE VALUES  Multi-Step Equations  Solve each equation. Check your solution.  1) 4x – 12 = -3x + 92) x – 8 = -33) 6(-x – 5) = -4(x – 3) – x  4) 3 – (2x + 9) = 175) Find the dimensions of the 20x - 48 rectangle, given the area is 7 504 square units

Solving Inequalities  Inequality symbols: Greater Than > and Less Than <  Multiplying / dividing by a negative number FLIP the inequality sign  OPEN circle when graphing / ≥, ≤ CLOSED circle when graphing Solve each of the following and graph the solution on the number line. 1) -3x + 9 < 122) 7x – 10 ≥ 113) x – 4 ≤ 84) -4 < 2x – 6 ≤ 8 5) -3x + 5 < -1 or 4x – 1 ≤ 3

Solving Absolute Value Equations  Isolate the bar term on one side of the equal sign  Set up TWO equations – one the same without the bars, the other the opposite of what is inside the bars  Solve each equation Solve each of the following: 1) 2) 3) 4)

Slope & Slope-Intercept Form
