  1. 1. Multi-Step & Compound Inequalities
  2. 2. Multi-Step Inequalities 1. 3x -2(6x - 4) > 4 - (4x + 6) 1. 3x -12x + 8 > -2 - 4x; -5x > -10; 2. 6x - 4 < 2x + 12 2. 4x < 16 x<4 3. 3x - 15 > 4 + 5x 3. -2x > 19; 4. x < - 19/2; x < - 9 1/2 x<2
  3. 3. Class Work: See Handout
  4. 4. Compound Inequalities If a compound inequality uses 'and', both inequalities must be true. The solution set is the intersection of the two inequalities. 1. Graph the solutions set of x < 2 and x > -1 The solution set is therefore: { x| -1 < x < 2}
