Inequalities

2
Inequality - a mathematical sentence that contains, or not equal. reads as greater than reads as less than < reads as less than or equal to > reads as greater than or equal to ≠ not equal to Inequalities and their graphs

3
When graphing inequalities use o Open circle used for Shaded circle used for >, <

4
Inequalities and their graphs- answers When graphing inequalities use o Open circle used for Shaded circle used for >, <

5
Inequalities and their graphs

6
Inequalities and their graphs- answers x < -7x > -11 x < 2 x > -3

7
Inequalities and their graphs

8
t < 16 h > 7 p < 25 n < 0

9
Solving One-Step Inequalities Examples: 1.x + 8 > 19 2. -26 > y + 14 3. m + 3 > 6 4. -5 < x -6 5. 4 + x 13

10
Solving One-Step Inequalities - ans Examples: 1.x + 8 > 19 2. -26 > y + 14 x > 11 y < -40 3. m + 3 > 6 4. -5 < x -6 m 1 5. 4 + x 13 y > 0

11
Solving One-Step Inequalities Examples: 1.x - 15 29 3. V - 4 11 5. -16 -11

12
Solving One-Step Inequalities - ans Examples: 1.x - 15 29 x 42 3. V - 4 11 v 16 5. -16 -2 6. X - 9 > -11 x > -2

13
Solving One-Step Inequalities by dividing and multiplying When dividing or multiplying by a negative number you must reverse (flip) the inequality sign
