2 **An inequality is a mathematics sentence that contains the following symbols: .You are watching: Mathematical sentence that contains an equal sign**, is much less than or same to is higher than or same to is less than is greater than > A systems to an inequality is any number that provides it true. Inequalities have many solutions. Solutions are presented by shading a number line.

3 **Graph each inequality equipment on a number line:**The open circle method the 1 is not consisted of in the solution. A. X The equipment is all numbers less than 1. The close up door circle method the −2 is had in the solution. B. The equipment is every numbers better than or same to −2.

4 **Solve this inequality and also graph the solution. X + 5 To fix an inequality, monitor the same actions you usage to settle an equation. Resolve this inequality and graph the solution. X − 5 − 5 Graph: x The systems is every numbers much less than 2. Check: shot 1, a number less than 2. X 1 + 5 6 This sentence is true. **

** 5 Solve this inequality and also graph the solution.x − − 5 Graph: x −2 The systems is all numbers better than or same to −2. Check: shot −1, a number greater than −2. −1 x − −5 −1 + (−3) −5 − −5 This sentence is true. **

6 **Solve this inequalities and graph the solution.**Try These: fix these inequalities and also graph the solution. X −2 −1 −1 Graph: x −3 x – 7 > – 5 Graph: + 7 + 7 x > 2

7 **Solve these inequalities and graph the solution.**3 x ≥ 9 Graph: x ≥ 3 Graph: ( 2 ) . . ( 2 ) x

8 **Solve this inequality and graph the solution.** 4 n > 16 n > 4 Graph:

9 **Solve this inequality and graph the solution.**2x − 8 > −10 2x > −2 2 2 x > −1 Graph:

10 **Write one inequality for each sentence.**In Florida you can vote if you room at the very least 18 years old. Compose an inequality reflecting the period of all voter in Florida. ( let x = the voter’s age) x You need to be much less than 16 year old come play ~ above a details youth baseball team. Write an inequality mirroring the age of the players. ( permit n = the player’ s age) n

11 **Write one inequality because that each sentence and solve it.See more: How Many Cups Of Raspberries In A Pint, How Many Raspberries In A Pound**Four times a number is much less than 12. 4 n Graph: 4 4 n The sum of a number and also 2 is at least 4. N Graph: −2 −2 n

12 **Use an inequality to settle problems.**A pair of jeans expenses $25 and a shirt prices $10. You have actually $50 to spend. Write an inequality to find how countless shirts you can buy along with one pair the jeans. ( permit n = the variety of shirts) 10n ≤ 50 −25 −25 10n ≤ 25 10 10 n ≤ 2.5 You deserve to buy 2 shirts.
