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

2x > 12

• x > 6

• x < 6

• x ≥ 6

• x ≤ 6

-3x ≤ 18

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.
