Finding Solutions to Inequalities

When graphing an inequality, we used an OPEN CIRCLE with which symbols?

• ≤, ≥ 

• <, >

Choose the solution to this inequality.

• z ≤ 1

• z > 9

• z ≤ 9

• z < 9

Which inequality will require us FLIPPING the sign when finding the solution?

• x - 2 > -18

• x + 2 > -18

• 2x > -18

• -2x > -18

We use inverse operations to solve equations AND inequalities.

• True

• False

• 3

• 6

• 8

• 10

Does the given value make the inequality true?  x + 9 > 21, when x = 15

• Yes, it is a solution.

• No, it is not a solution.

Which value will satisfy the inequality?
x + 5 ≤ 13

• 8

• 18

•  65

• There is no solution.

• 6

• 7

• 9

• 10

• 10

• 15

• 20

• 25

• 18

• 19
