  3. Write in 2 different set notations: the set of all negative even integers

  4. {-2,-4, -6, -8….}{x | x is even and x<0}

  5. What is the intersection of the set of people in this room with brown hair and people in this room wearing blue?

  6. What is the union of natural numbers and 0?

  7. {0, 1, 2, 3, ….}{x|x is a whole number}

  8. Answer

  9. Let R be the set of Real Numbers and Q be the set of Rational Numbers. Find R∩U.

  10. {x|x is a rational number}

  11. If A = {Natural numbers}B={odd integers < 0}C={integers that are multiples of 3}Find A∪B∩C

  12. {C}

  13. Write the solution to the following inequality in interval notation: -14 -3 4

  14. (-00, -14] U (-3, 4) U (4, 00)

  15. Write an inequality for the graph below: 8 -15

  16. -15≤x<8

  17. What is the solution to the following inequality?-2x+1<5 and -2x+10>2 -2 4

  18. No Solution

  19. Name 2 possible solutions and one non-solution to the following inequality:

  20. Answer

  21. Write an inequality for the graph below:

  22. y≤-5/3x-5

  23. Solve:-2x<-2 or -3x-1<2

  24. Possible solutions: every number except -1 x<-1 or x>-1

  25. Solve and graph:-45 < 4x-5 < -37

  26. -10 < x < -8 -10 -8

  27. Solve and write your solution in interval notation: |x+4|< 2

  28. x<-2 or x>4(-00, -2) U (4, 00)

  29. Solve and state whether it is a disjunction or a conjunction:|2a-1|+3 < 8

  30. -2 < a < 2Conjunction

  31. Solve, graph, and write in interval notation:|-3y+6|> 12

  32. y < -2 or y > 6(-00,-2] U [6, 00) -2 6

  33. What are the possible solutions to:|c|= d

  34. c, -c

  35. Solve: |4x-9| = -7

  36. No Solution

  37. Solve:-8|6 - z|-14 = 50

  38. No Solution

  39. Solve:

  40. 63/11, -3

  41. Solve: -2|24-3r|=18r-12

  42. r= -3

  43. Is (-4,0) a solution to the system of inequalities below. Why?:

  44. No. Because it is where the lines intersect, but the lines are dotted, which means the points on the line are not included in the solution

  45. Solve the system of inequalities by graphing:y < xx > 5

  46. Solve the system of inequalities by graphing:y-x+2<02y-2>x

  47. Write a system of inequalities for the graph below:

  48. y < 3x > -4
