inequalities

When solving inequalities, when do you flip the inequality symbol?

• When the solution is a negative.

• When you multiply or divide both sides of the inequality by a negative number.

• When you multiply both sides of the inequality by any number.

• When you divide both sides of the inequality by a positive number.

Match the graph with its inequality.

• a > 11

• a < 11

• a ≥ 11

• a ≤ 11

• ≤, ≥ 
• <, >
• ≤, <
• ≥, >
