1. Do Now Solve each inequality. −3e − 10 ≤ −4 2.
3. 8c + 4 > 4(c − 3) −8 + 4a −12 > 2a + 10

2. Any Questions on the Homework?
Did you check your answers while you worked? Will you ace the quiz we’re having next Thursday and Friday?
Also, shameless Key Club plug.

3. Review: Graphing an Inequality on a Number Line
How would you graph:
X < 7
≥ x

4. What If Two Inequalities Were True?
Combining two or more simple inequalities forms a compound inequality. The graph of a compound inequality involving AND is the intersection, or the overlapping region, of the simple inequality graphs.

5. Examples (these are for your notes)
Solve each compound inequality and graph the solution.
4 ≤ x + 2 ≤ 8

6. Another Example Solve each compound inequality and graph the solution.
B. -5 ≤ 2x + 3 < 9

7. Your Turn Solve each compound inequality and graph the solution.
-2 < x - 3 < 5
< 3x + 2 ≤ 8

8. Solving Compound Inequalities Involving OR
The graph of a compound inequality involving OR is the union, or the combined region, of the simple inequality graphs.

9. Examples of OR Inequalities
Solve each compound inequality and graph the solution.
-4 + x > 1 OR -4 + x < -3
B. 2x ≤ 6 OR 3x > 12

10. Your Turn Solve each compound inequality and graph the solution.
x - 5 ≥ -2 OR x -5 ≤ -6
2. 4x -1 < 15 OR 8x ≥ 48

11. Creating Compound Inequalities from Graphs
Write the compound inequality shown by each graph. B.

12. Your Turn
Write the compound inequality shown by each graph. 2.

13. Let’s Try a Word Problem
But we’ll pick one or two from the homework :)
