  1. Warmups Translate: The product of 7 and m is at most 10 Solve and graph each inequality:

  2. 7-4 Compound Inequalities Objective: To solve and graph “or” inequalities

  3. Compound Inequality • More than one • “and” “or” today Example 1: x > 2 or x < -4 Graph on the same number line: These answers or These answers

  4. Example 2 • Graph x < 2 or x > 6

  5. TOO • x < -3 or x > 4 • x > 5 or x < 0 • x > -5 or x < -7

  6. Write your own… Write a compound inequality for each solution set shown below: 3. 4. -2 3 0 0 5

  7. What about… 5. x < 4 or x > -3 • x > 3 or 4 < x • x – 2 < 0 or 2x + 4 > 8 “All numbers”

  8. TOO – Solve and graph • 4x – 5 > 7 or 4x – 5 < -9 • -1 + x < 3 or –x < -4 • 3n + 11 < 13 or 2n > 5n - 12 x > 3 or x < -1 All numbers n < 4

  9. AND vs. OR

  10. Homework • Pg. 410 # 26, 27, 28, 31, 33, 37, 38, 40, 41, 42

  11. Math Lab Inequalities Review Tic Tac Toe

  12. AND vs. OR

  13. Translate • The difference of x and 3 is more than 7. • The product of 3 and y is at least 10. • A number decreased by 5 is at least 13. • Twice a number is less than or equal to the number increased by 3 • A number decreased by 8 is at most 1.

  14. Solve and graph No solution

  15. Solve and graph or -1 1 0

  16. Solve and graph and x<1 1

  17. Solve and graph y > -1 and y < 3 -1 3

  18. Solve and graph or All numbers

  19. Solve and graph Write a compound inequality for each solution set shown below: 3. -3 6 0

  20. Solve and graph Write a compound inequality for each solution set shown below: 0 5
