Graph the solutions of the inequality on a number line. 26. c < 5 27. -8 > q 28. Write an inequality for the graph <-------------------------------> (-5 -4 -3 -2 -1 0 1 2 3 4 5) Open circle on 3...4 and 5 are shaded 29. A road had a speed limit of 30 mi/h. Write an inequality that describes the legal speeds r for motor vehicles. Solve the inequality. Graph the solutions. 30. a + 4 >(underlined) 8 31. 9 - 7 > 0 Solve the inequality 32. 5n > -25 33. 42 < -6d 34. r/6 <(underlined) 3 35. 6/-6 > 10 Please answer all of these.. thnxx :) |

In #26, if you replace the variable c with x<5, you can get the plot in the 1D inequality graphing calculator: http://webgraphing.com/inequality_1d.jsp The same is true for many of the items> #27. enter -8>x for the graph #30. enter x+4>=8 #31 for 9-7>0 this means 2>0 which is always true to the whole real line is the graph #32. enter 5x>-25 Hope these ideas help jump start you. ---------------------------------------- Principal Skinner |
