I am having technical difficulties posting imiages at this time, so I'll do my best at typing answer to the chapter 3 part B test review.
1. {6, 12, 18}
2. {1,2,3,4,5,6}, {x l x is a positive integer, x<7}
3. -3<n<=5
4. 0.25>=k>=-2
5. y<-6 or y>2
6. p>=9 or p<3
7. 82 <=x<=89
8. 45 <= speed <= 60
9. 450 < 15h < 600
10. {}, {3}, {5}, {7}, {3, 5}, {3, 7}, {5, 7}, {3, 5, 7}
11. x=5, -5
12. a>4 or a<-6
13. Z=5, -1
14. -16<=v<=1
15. -2<=x<3
16. x<=0 or x>1
17. 69 to 73
18. {2, 3, 5, 7, 8, 9, 11, 13}
19. 30
20. l x + 1.5 l = 4.5 *** this will not be on the test***
21. you cannot get a negative value from an absolute value, and you would need a negative to add with a 7 to get a sum of 2.
