10. x ≥ 4 or x < 2
Solve the inequality and graph its solution. 11. 2x 9 > 17 or 5x 10 < 10
12. 3x 6 ≥ 0 or 4x 5 ≤ 3
13. 7 > 1 x or 2x 1 < 25
14. 4 5x > 24 or 16 x ≤ 17
15. x 2 ≤ 5 or x 4 ≥ 2
16. 15 7x ≤ 6 or 6x 3 < 6
17. 3x 2 < 10 or 2x 4 > 4
18. 2x 1 > 13 or 18 > 7x 3
Solve the inequality and graph its solution. Then check graphically whether the given x-value is a solution by graphing the x-value on the same number line. 19. 7 ≥ 3 2x or 3x 5 < 20; x 1
20. 8 > 2x 4 or 3 x ≤ 6; x 3
21. 4 3x ≤ 8 or 3x 1 ≤ 8; x 0
22. 5x 1 < 14 or 6x 1 > 7; x 3
23. A certain museum is free for children under 3, half-price for children ages 3
through 12 and for senior citizens ages 65 or over, and full-price for anyone who is over 12 and under 65. Write an inequality to describe a, the ages in years of museum visitors who do not need to pay full price.
