Adding and Subtracting Linear Inequalities

Variables on Each Side Write an Inequality to Solve a Problem

Solve 3p – 6 ≥ 4p. Graph the solution. Michael scored 30 points in the four rounds of the
free throw contest. Randy scored 11 points in the
first round, 6 points in the second round, and 8 in
A. {p | p ≤ –6} the third round. How many points must he score in
the final round to surpass Michael’s score?
–9 –8 –7 –6 –5 –4 –3
B. {p | p ≤ –6} A. 30 points
B. 5 points
C. 7 points
–9 –8 –7 –6 –5 –4 –3 D. 6 points
C. {p | p ≥ –6}
Answer

–9 –8 –7 –6 –5 –4 –3
D. {p | p ≥ –6}

–9 –8 –7 –6 –5 –4 –3

Skill Practice!

Match each inequality with its corresponding graph.

1. x + 11 > 16 a.

2. x – 6 < 1 b.

3. x + 2 < –3 c.

4. x + 3 > 1 d.

5. x – 1 < –7 e.
