Inequalities with Multiplying and Dividing

• h > 10
• h > -10
• h < 10
• h < -10

Solve and graph for x.

• x > 30, open circle at 30, arrow goes to the right

• x > 2430, open circle at 2430, arrow goes to the right

• x < 30, solid circle at 30, arrow goes to the right

• x > 30, solid circle at 30, arrow goes to the right

Solve and graph for c. 

• c ≥ 25, solid circle, arrow going to the right

• c ≥ 25, open circle, arrow going to the right

• c ≥ 25, solid circle, arrow going to the left

• c ≥ 25, open circle, arrow going to the left

• c ≥ -42
• c ≥ 42
• c ≤ -42
• c ≤ 42

This inequality needs to be flipped. Choose the reason why:

When solving inequalities, if you multiply or​ ​ (a)   both sides by a ​ (b)   number, you must ​ (c)   the ​ (d)   symbol.

• divide

• negative

• flip

• inequality

• v < -12

How would you solve the inequality?

• Multiply

• Divide

Would you reverse the sign?

• Yes, the x is hanging out with a negative

• No, the x is hanging out with a positive
