Learning Inequalities

Choose the correct inequality for the graph:

• x < 3 or x > 5

• x < 3 or x > 5

• x < 3 and x > 5

• x < 3 and x > 5

Solve:
 |x + 3| > 8

• x > 5 or x < -11

• x > 5

• all real numbers

• no solution

Solve.
|p + 3| ≥ 10

• -13 ≤ p ≤ 7

• p ≤ -13 or p ≥ 7

• -7 ≤ p ≤ 13

• p ≤ -7 or p ≥ 13

What is the first step?

• Get the absolute value alone by dividing both sides by 5

• Drop the absolute value bars and add 7 and 5 together

• Get the absolute value alone by subtracting 5 from both sides

When graphing b < 6 would you use an open or closed circle?

• Open

• closed
