Inequalities

When do you "flip the inequalities sign"?

• When you add or subtract a negative

• When it's a 1-step problem

• When you multiply or divide a negative

• When it's a 2-step problem

Solve 5x + 9 > 34

• x > -5

• x > 5

• x < -5

• x < 5

Solve -2x - 3 ≤ 13

• x ≥ 8

• x ≥ -8

• x ≤ 8

• x ≤ -8

When do you use a closed circle on a graph for an inequality?

• When it is ≥ or ≤

• When it is > or <

• When the number in front of the variable is negative

• When it is only =

Match the graph with its inequality.

• b > –2
• b < –2
• b ≥ –2
• b ≤ –2

Pick the correct letter for:

x < 6

• A

• B

• C

• D

When graphing an inequality, you use an OPEN dot when you use which symbol?

• <, >
• ≤, ≥ 
• ≤, <
• ≥, >
