Presentation Transcript

  1. 4-5 Inequalities (pages 172-175) P6  Represent inequalities on a number line or a coordinate plane.

  2. Inequalities

  3. Examples • What do the following mean? 1) a > 5 2) t ≥ 2/3 • What are some examples that make each true? • What are some examples that make each false? • Draw a number line to represent the solutions

  4. Solve the following inequalities and graph the solutions on a number line • 1) 4x + 5 < 21 2) 2x - 6 ≥ 5

  5. You Try…

  6. Write an inequality for each sentence. Then solve the inequality. Eight times a number is less than 24. Eight less than a number is greater than or equal to 12. + 8 + 8
