6.4 Solving Compound Inequalities I can… solve compound inequalities containing the word and and graph their solution sets. I can… solve compound inequalities containing the word or and graph their solution sets.
Inequalities with AND The solution set is the area where it is true for BOTH inequalities. Symbol: Intersection EX. x < 2 and x -1
Inequalities with OR The solution set is the area where it is true for ONE OR BOTH of the inequalities. Symbol: U Union EX. 2a + 1 < 11 or -2a < 2
Examples: A.)Graph the solution set of y 5 and y < 12.
Examples: B.)Solve 7 < x Then graph the solution set.
Examples: C.)Solve and then graph the solution set. 4k – 7 25 or 12 – 9k 30.
