1.7 Solving Inequalities Warm-up (IN) Learning Objective: to write, solve and graph compound and single variable inequalities. 1. Graph and label the points on the same number line. a.-1 b. 3.5c. -9/4 d. 0 2. Graph each inequality on a separate number line.

2
Notes Ex 1 – Solve and graph the inequalities FLIP THE INEQUALITY!!! (when mult or div by neg.) Dr. Burger VideoVideo

3
Ex 2 – If tests are 60% of your grade and HW is 40% and your test average is 85, what HW average do you need to have to get an A in the class? Final grade = Test avg (60%) + HW avg (40%) 90= 85(0.6) + x (0.4) 90= 51 + 0.4x 39= 0.4x x = 97.5 Compound Inequality – A pair of inequalities joined by “and” or “or”

4
“And” – the solution must satisfy BOTH inequalities Ex 3 – Solve and graph “or” – the solution must satisfy AT LEAST ONE of the inequalities Ex 4 – Solve and graph

5
HW – p. 57 #4,10,11,20-22,38-40,52-58 even, 73,76,81,84 Out – Solve and graph Summary – Today’s lesson was… POW!!
