1 5 Minute Check Complete on the back of your homework. An African elephant eats 400 lbs of vegetation each day. 1. Write an equation to find v, the number of pounds the elephant eats in d days. 2. Make a table to show the relationship between the number of pounds v the elephants eats in d days. 3. List the ordered pairs for the first three days. 4. If the ordered pairs were graphed, would it be linear?

11 Wednesday, Jan 29 Chapter 8.5 Inequalities

12 Objective: To solve inequalities using mental math and the guess, check and revise method.

13 Inequalities At the end of this lesson you should be able to answer the following question. How can mental math help you find solutions to inequalities?

14 Inequalities An inequality is a mathematical sentence that compares quantities.

15 Inequalities This symbol means what? >

16 Inequalities This symbol means what? > means greater than This symbol means what? <

17 Inequalities This symbol means what? > means greater than This symbol means what? < means less than

18 Inequalities This symbol means what? >

19 Inequalities This symbol means what? > means equal to or greater than

20 Inequalities This symbol means what? > means equal to or greater than This symbol means what? <

21 Inequalities This symbol means what? > means equal to or greater than This symbol means what? < means equal to or less than

22 Inequalities Give an example if a number less than 5.

23 Inequalities Give an example if a number less than 5. Any number that is to the left 5, is less than 5.

24 Inequalities Of 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.

25 Inequalities Of 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.

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

27 Inequalities Of the numbers 8, 9, or 10, which is the solution for the inequality n -3 > 6? 10 – 3 > 6 7 > 6 7 is the only solution.

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

29 Inequalities Is the given value a solution for the inequality? x + 3 > 9; x = 4 4 + 3 > 9 7 > 9 4 is not a solution.

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

31 Inequalities Is the given value a solution for the inequality? 12 < 18 - y; y = 6 12 < 18 - 6 12 < 12 6 is a solution.

32 Inequalities Is the given value a solution for the inequality? 17 > 11 + x; x = 8 Do this on your own.

33 Inequalities Is the given value a solution for the inequality? 17 > 11 + x; x = 8 17 > 11 + 8 17 > 19 8 is not a solution.

34 Inequalities Lisa works at a gift shop. She receives a bonus if she makes more the 20 balloon bouquets a month. Which months did she receive her bonus? Use the inequality b > 20, where b equals the number of balloon bouquets made each month to solve. Do this on your own.

35 Inequalities Lisa works at a gift shop. She receives a bonus if she makes more the 20 balloon bouquets a month. Which months did she receive her bonus? Use the inequality b > 20, where b equals the number of balloon bouquets made each month to solve. Since 25 > 20 and 32 > 20, She received the bonus in July and October.

36 Inequalities If the bakery sells more than 45 bagels in a day, they make a profit. Use the inequality b > 45 to determine which days the bakery made a profit. Do this on your own.

37 Inequalities If the bakery sells more than 45 bagels in a day, they make a profit. Use the inequality b > 45 to determine which days the bakery made a profit. Since 50 > 45 and 48 > 45; They made a profit on Friday and Saturday.
