InequalitiesInequalitiesObjective: To solve inequalities using mental math and to write and graph inequalities.

InequalitiesAn inequality is a mathematical sentence that compares quantities.

You will need your number line for todays lesson.InequalitiesThis symbol means what?>InequalitiesThis symbol means what?> means greater than

This symbol means what? means greater than

This symbol means what?< means less thanInequalitiesThis symbol means what?>InequalitiesThis symbol means what?> means equal to or greater than

InequalitiesThis symbol means what?> means equal to or greater than

This symbol means what? means equal to or greater than

This symbol means what?< means equal to or less thanInequalitiesOf the numbers 6, 7, or 8, which is the solution for the inequality f + 2 < 9?

To solve this, substitute 6,7, and 8 for the variable f to make a true statement. InequalitiesOf the numbers 6, 7, or 8, which is the solution for the inequality f + 2 < 9?

To solve this, substitute 6,7, and 8 for the variable f to make a true statement.

6 + 2 < 9; 6 is the only solution.InequalitiesOf the numbers 8, 9, or 10, which is the solution for the inequality n -3 > 6?

Do this on your own. InequalitiesOf the numbers 8, 9, or 10, which is the solution for the inequality n -3 > 6?

10 3 > 6 7 > 6

10 is the only solution. InequalitiesIs the given value a solution for the inequality? x + 3 > 9; x = 4

Do this on your own.InequalitiesIs the given value a solution for the inequality? x + 3 > 9; x = 4

4 + 3 > 9 7 > 94 is not a solution.InequalitiesIs the given value a solution for the inequality? 12 < 18 - y; y = 6

Do this on your own. InequalitiesIs the given value a solution for the inequality? 12 < 18 - y; y = 6

12 < 18 - 612 < 12

6 is a solution.InequalitiesLulsa works at a gift shop. She receives a bonus if she makes more than 20 balloon bouquets in a month. Which months did she receive a bonus? Use the inequality b > 20, where b represents the number of balloon bouquets made each month.

InequalitiesLulsa works at a gift shop. She receives a bonus if she makes more than 20 balloon bouquets in a month. Which months did she receive a bonus? Use the inequality b > 20, where b represents the number of balloon bouquets made each month.

The only months greater than 20 are July and August.

InequalitiesIf a bakery sells more than 45 bagels in a day, they make a profit. Use the inequality b > 45, to determine which days the bakery makes a profit.

InequalitiesWrite an inequality for the sentence below.A number less than 5. InequalitiesWrite an inequality for the sentence below.A number less than 5. A < 5(Any number that is to the left of 5 on the number line, is less than 5)

We can also graph this on a number line.InequalitiesWrite an inequality for the sentence below.A number less than 5. A < 5

Any point on the blue line is a solution to the inequality. InequalitiesWrite an inequality for the sentence below.A number less than 5. A < 5

Anytime an inequality with < or > is graphed, an open dot is used.

Write this downInequalitiesWrite and graph an inequality for the sentence below.A number greater than -8.

InequalitiesWrite and graph an inequality for the sentence below.A number greater than -8.A > -8Any number that is to the right of -8 on the number line, is greater than -8.

InequalitiesWrite and graph an inequality for the sentence below.A number greater than -8.A > -8Notice the inequality sign faces the same direction as the arrow on the graph.
