Module 6 topic 1 notes

  1. 1. Solving One-Step Inequalities 7 6 3 5 4 2 8
  2. 2. Objective: To solve one-step inequalities using properties for inequalities Solving One-Step Inequalities
  3. 3. Solving One-Step Inequalities What are the Properties for Inequalities? Are they the same as for regular equations?
  4. 4. Solving One-Step Inequalities Addition Property for Inequalities X-15<73 X-15+15<73+15 X<88 Add 15 to both sides
  5. 5. Solving One-Step Inequalities Subtraction Property for Inequalities y+15<25 Y+15-15<25-15 y<10 Subtract 15 from both sides
  6. 6. Solving One-Step Inequalities Multiplication Property for Inequalities Multiply both sides by the reciprocal of the coefficient
  7. 7. Solving One-Step Inequalities Division Property for Inequalities Divide both sides by the coefficient of x
  8. 8. Division Property for Inequalities Caution! Dividing by a negative number Same if multiplying? Notice: Sign CHANGED
  9. 9. Multiplication Property for Inequalities Caution! When you multiply by a negative number… YES! - x > 2 5 (- 5 )- x > 2(-5) 1 5 x < -10 … the sign CHANGES
