Exploring Solution Sets of Compound Inequalities

What is a compound inequality?

• An equation with two variables

• Two separate inequalities connected with 'and' or 'or'

• A single inequality with a complex solution

• An inequality that cannot be solved

When solving the inequality -2x + 5 < 9, what is the first step?

• Subtract 5 from both sides

• Multiply both sides by -2

• Divide both sides by 2

• Add 5 to both sides
