2. Solve the linear inequality. Other than ∅, use interval notation to express the solution set and graph the solution set on a number line.
− 6(5x + 7) < −36x − 6
3. Solve the problem. When making a long distance call from a certain pay phone, the first three minutes of a call cost $2.40. After that, each additional minute or portion of a minute of that call costs $0.30. Use an inequality to find the number of minutes one can call long distance for $4.20.
4. Use graphs to find the set.
a) (-7, 0) ∩ [-4, 2]
b) (-10, 0) ∪ [-1, 5]
