3. Graph: x < 2 x ≤ -2 x > - 4 x ≥ 3

4. When you multiply or divide by a negative number, you must flip the inequality symbol!!!

5. -2x + 7 < 17 - 7 - 7 -2x < 10 -2 -2 x > -5

6. 2x + 3 < 5 OR -3 -3 2x < 2 2 2 x < 1 4x – 2 > 10 + 2 +2 4x > 12 4 4 x > 3 x 3

7. -2 ≤ 3x – 8 ≤ 10 +8 + 8 + 8 6 ≤ 3x ≤ 18 3 3 3 2 ≤ x ≤ 6

8. The high temperature on a certain day was 98°F and the low was 78°F. Write a compound inequality that models the range in temperatures. 78 ≤ x ≤ 98

9. x  3x  3 x  2   5 x  2   5 x  7 Solve | x  2 |  5 The equation has two solutions: 7 and –3.

10. x + 5 can be any number between -6 and 6. -6 < x + 5 < 6 -5 - 5 -5 -11 < x < 1

11. Positive x – 4 > 3 +4 +4 x > 7 Negative x – 4 < -3 +4 +4 x < 1 x – 4 can be anything bigger than 3 or smaller than -3. OR x > 7 OR x < 1

12.  an arrangement of digits that is used to display and order numerical data.  Example: StemLeaves 24 6 6 9 30 4 7 41 2 2 5 7 9 52 4 5 5 8 Key: 2|4 = 24

13.  a data display that divides a set of data into four parts. Minimum 1 st Quartile 3 rd Quartile Median (2 nd Quartile) Maximum
