  4. Less ThAND AND AND

  5. Your Turn… Solve | 2x + 3 | < 6. Make two cases. Solve the two cases independently.


  6. Your Turn… Solve | 2x – 3 | > 5. Make two cases. Solve the two cases independently.

  7. Find the absolute-value inequality statement that corresponds to the inequality –2 < x < 4. Challenges… HINT: Think midpointand distance. Find the absolute-value inequality statement that corresponds to the inequalities x < 19 or x > 24.
