1. 4-8 COMPOUND INEQUALITIES MISS BATTAGLIA – ALGEBRA 1 CP OBJECTIVE: SOLVE COMPOUND INEQUALITIES AND ABSOLUTE VALUE INEQUALITIES AND GRAPH THE SOLUTIONS ON A NUMBER LINE.

2. WARM UP Which is larger: x 5, y 4, or z 3, where x = 2, y = 3, and z = 4?

3. COMPOUND INEQUALITIES JOINED BY “AND” 32 < t and t < 40 32 < t < 40 t is greater than 32 and less than 40 t is between 32 and 40 Today’s temperatures will be above 32 o F, but not as high as 40 o F.

4. GRAPH The graph of 32 < t < 40 is an interval on a number line 32 < t < 40

5. SOLVE & GRAPH Two inequalities that are joined by the word and or the word or are called compound inequalities. -4 < r – 5 < -1

6. SOLVE & GRAPH -3 < j + 2 < 7

7. SOLVE & GRAPH 4v + 3 < -5 or -2v + 7 < 1

8. SOLVE & GRAPH 4 + k > 3 or 6k < -30

9. SOLVE & GRAPH 12 > -3x and -2x > -12
