Presentation on theme: "Fill in the blank with <, >, or = to make each statement true."— Presentation transcript:

1 Fill in the blank with <, >, or = to make each statement true.
1 finger if < 2 fingers if > 3 fingers if = 2  3

2 5  4 1 finger if < 2 fingers if > 3 fingers if =

3 3  -5 1 finger if < 2 fingers if > 3 fingers if =

4 1 finger if < 2 fingers if > 3 fingers if = -2  -5 -6

5 -7  -4 1 finger if < 2 fingers if > 3 fingers if =

6 1 finger if < 2 fingers if > 3 fingers if =

7 Thumb down if not a solution
x < 3 Is a solution? Thumb up if yes Thumb down if not a solution

8 Thumb down if not a solution
x < 3 Is a solution? Thumb up if yes Thumb down if not a solution

9 Graph the solution of x < 3
2.999 -2 -6 -4 6 4 2 -2 -6 -4 6 4 2

10 Graph the solution of x + 3 = 7
-2 -6 -4 6 4 2

11 Graph the solution of x  -2
-6 -4 6 4 2

12 Graph the solution of x  |-2|
-6 -4 6 4 2

13 Inequalities  “less than or equal to”  “less than”  “greater than”
 “greater than or equal to”

14 QQ. Write the equation for each graph
1 2 3 4 5 -2 -6 -4 6 4 2 -2 -6 -4 6 4 2 -2 -6 -4 6 4 2 -2 -6 -4 6 4 2 -2 -6 -4 6 4 2

15 Inequalities vs. Equations Solutions
Inequality Equation x + 5  9 x + 5 = 9 x = 4 x = 4 x = 5 x = 6 x  4

16 Addition Property of Inequalities
13 < 25 +2 +2

17 Addition Property of Inequalities
13 < 25 +100 +100

18 Addition Property of Inequalities
13 < 25 -13 -13

19 Addition Property of Inequalities If a < b, then a + c < b + c
“If I add the same number to both sides of an inequality, I get another TRUE inequality in the same direction.” The same is true for >,  , and 

20 Solve for “x”and graph: 5x + 2  4x + 7
-4 -8 8 4

21 Solve for “x”and graph: -2(x - 7) > 2x - 6
Check with ZERO -4 -8 8 4

22 Solve for “y”, then graph the solution.
-2 -6 -4 6 4 2

23 Solve for “y”, then graph the solution.
-3 -3 y  -4 -2 -6 -4 6 4 2

24 3 < 5 (-3) (-3) -9 < -15 ??? -9 > -15

25 Multiplication Property of Inequalities
For all rational numbers a, b, and c: When c is positive, if a > b, then a • c > b • c When c is negative, if a > b, then a • c < b • c If you multiply or divide an inequality by a negative number, reverse the inequality sign in the answer.

26 If you multiply or divide an inequality by a negative number, reverse the inequality sign in the answer.

27 Solve for “y”, then graph the solution.
-3 -3 y  -4 -2 -6 -4 6 4 2

28 Solve for “y”, then graph the solution.
-2 -6 -4 6 4 2

29 QQ: Solve for x. Graph # 4 3x  18 14x  -7 -8x > 32 -5x < 30
A,C,E,G B,D,F 1 3x  18 14x  -7 2 -8x > 32 -5x < 30 3 9x  -3 7x > 49 4 -6x < -36 -4x  -24

30 2-Step Inequalities 6 + 5y > 21 -6 + 6 + 5y > -6 + 21 5y > 15

31 7x + 4  4x + 16 x  4 -2 -6 -4 6 4 2

32 13a + 5  12a + 4 -2 -6 -4 6 4 2

33 4m – 4 > 8 + 2m -2 -6 -4 6 4 2

34 -6x + 7 – x + 1 < 2x + 4 -7x + 8 < 2x + 4 +7x - 4 - 4 +
-2 -6 -4 6 4 2
