Lessons that teach this standard

• How to Solve Absolute Value Equations

  Solve absolute value equations by splitting into two cases, why two answers appear, when there is no solution, and how absolute value inequalities differ.

• How to Solve Compound Inequalities (AND and OR)

  Solve compound inequalities joined by AND or OR, graph the solution on a number line, and tell which combinations give no solution or every number.

• How to Solve Multi-Step Inequalities

  Solve multi-step inequalities by distributing, combining like terms, and undoing operations in reverse order, including when to flip the inequality sign.
