  1. Ch 1 Connections to Algebra -variables, exponents and powers, order of operation, equations and inequalities, tables and graphs Ch 2 Properties of Real Numbers -addition, subtraction, multiplication, division, matrices, probability and odds Ch 3 Solving Linear Equations -adding and subtracting, multiplying and dividing equations, decimal equations, formulas, rates, ratios, percents Ch 4 Graphing Linear Equations and Functions -coordinates and scatter plots, quick graphs with intercepts, slope, direct variation, quick graphs using slope-intercept, solving equations by graphing, functions and relations Ch 5 Writing Linear Equations -using slope-intercept form, given slope and a point, given two points, best fitting line, point-slope form, standard form, predicting with linear models

  2. Ch 6 Solving and Graphing Linear Inequalities See p384-386 for preview 6.1 Solving One-Step Linear Inequalities

  3. Solving one-step linear inequalities Solve x + 8 > 1 and graph the solution Solve 3 < m – 5 and graph the solution

  4. When you multiple or divide by a negative number, you must reverse the sign.

  5. 6.2 Solving Multi-step Linear Inequalities 5x – 3 > 12 -3x + 1 < 22 -x + 1 < 3x + 21

  6. 6.2 p343-345 #16-32 every 4th one, 39,43-48

  11. No two sides when added together can be shorter than the 3rd side. No one side can be longer than the other two sides added together. x < s1 and s2 long side< x + short side long side < other two sides, and x < other two sides 47. 7 ½ < x + 3 ¼ and x < 3 ¼ + 7 ½ 4 ¼ < x and x < 10 ¾ 4 ¼ < x < 10 ¾ 48. 11.75 < x + 5.5 and x < 5.5 + 11.75 6.25 < x and x < 16.25 6.25 < x < 16.25
