Solving Compound Inequalities Effectively

What is the first step in solving compound inequalities?

• Ignore the inequality signs

• Combine the inequalities into one

• Break the compound inequality into two separate inequalities

• Graph the inequalities immediately

When solving an inequality, what must you remember to do if you multiply or divide by a negative number?

• Add the same number to both sides

• Subtract the same number from both sides

• Reverse the inequality symbol

• Keep the inequality symbol the same
