1.5 Part Solving Inqualities

• (7-25) odd
• (27-30) all
• (31-37) odd
• remember, the steps to solving a compu=ound inequality are:
• 1. solve each inequality
• 2. graph your PRELIMINARY graph
• 3. answer the appropriate question:
• for "and" problems: what numbers are highlighted by BOTH colors?
• for "or" problems: what numbers are highlighted by your ONE line?
• 4. write your solution and make a final graph.
• 28: I
• 30: 3(x-2) + 8 = 12
• 3x-6 + 8 = 12 distributive property
• 3x + 2 = 12 substitution property
• 3x = 10 subtraction property
• x = 10/3 division property
