1. Warm-Up Let A = {0,1,3,8}, B = {2,4,5,6,7,9}, and C = {0,1,8}. 4 minutes Find the following sets.

2. 9.2.1 Compound Sentences 9.2.1 Compound Sentences Objectives: To solve and graph a conjunction of two inequalities in one variable

3. Conjunctions A sentence like x > 5 and x < 12 is called a conjunction. A conjunction of two statements is formed by connecting them with the word “AND.” A conjunction is true when both statements are true.

4. Example 1 Graph the conjunction x 2. 45678321

5. Example 2 Graph the conjunction 2 < x < 7. 45678321 x > 2andx < 7

6. Practice Graph each conjunction. 1) -3 < x and x < 4 3) -2 < x < 5

7. Example 3 Solve and graph. 910111213876 + 5

13. Disjunctions A sentence like x 12 is called a disjunction. A disjunction of two statements is formed by connecting them with the word “OR.” A disjunction is true when one or both statements are true.

14. Example 1 Graph the disjunction x 6. 45678321

15. 01234-2-3 Example 2 Graph the disjunction x < -2 or x 2.

16. Practice Graph each disjunction. 1) -3 > x or x > 4 3) -2 < x or x < 3

17. 45678321 Example 3 Graph the disjunction 2x – 1 10. 2x – 1 < 5or3x – 5 > 10 + 1 2x < 6 22 x < 3 + 5 3x > 15 33 x > 5

18. Practice Solve and graph. 1) -2x – 6 > 4 or x + 5 > 8 2) -5x + 2 > 27 or x – 3 > 2
