Graphing and Two-Step Inequalities

Solve for f.

23 < f + 12

• f > 11

• f > 35

• f < 35

• f < 11

When graphing an inequality, you use an open circle when you use which symbols?

• <, >

• ≤, ≥

When you graph an inequality, you use a closed circle when you use which symbols?

• ≤, ≥

• <, >

Pick the correct letter for:
6 > x

• A

• B

• C

• D

Solve for k in the following inequality and choose the best answer to match the graph: 2k - 9 ≤ -19

• The graph would have a closed circle shaded left at -5.

• The graph would have a closed circle shaded left of 5.

• The graph would have an open circle shaded left of -5.

• The graph would have an open circle shaded left of 5.

Let's kick it up a notch. Use what you know about distributing and solving two-step inequalities when solving for n.

6(n + 2) < -72

• n < -14

• n < 35/3

• n < -10

• ∞

Let's kick it up another notch. Use what you know about distributing, combining like terms and solving two-step inequalities when solving for x.

7(x + 3) - 5x < 13

• x>-4

• x < 17

• x<-4

• x > -17
