Solve: x+2<13 and x+20<24 what is there intersection? | (-∞,4) |
Solve: -2<-3x-8<4 Put the solution set in interval notation. | (-4,-2) |
A{x[x is an odd number greatern than 0 and less than 20} B={3,6,9,12,15,18}, Find the union between the A and B sets | A ∪ B {1,3,5,6,7,9,11,12,13,15,17,18,19} |
Solve: 3x≥0 5x-2≤-7 | There is no number Ø |
Solve: -3x+2<8 or 9x<0 What is the solution set? | (-2,∞)or(-∞,0) |
