Compound Inequalities

Which of the following would result in NO SOLUTION?

• x < 1 or x > 5

• x > 1 or x < 5

• x < 1 and x > 5

• x > 1 and x < 5

Solve and give the final solution set:

5x + 1 < 21 OR 3x + 2 > -1

• All real numbers

• -1 < x < 4

• No solution

• x > 4 or x < -1

Express the following in Interval Notation. (Sketch a graph first if it helps.)

-8 ≤ x < 8

• [-8, 8]

• [-8,8)

• (-8, 8]

• (-8, 8)

Look at the graph. Write the inequality in interval notation.

• (-2,5)

• (-∞,-2)⋃(5,∞)

• [-2,5]

• (-∞,-2]∪[5,∞)

Look at the picture. Which number line corresponds to [-2, 5]?

• Graph 1
