1. Classifying types of numbers
89
–4
= 4
≈3.3166…
R, Q, Z, W, N
R, Q
R, Q, Z
R, I
2. Identify the Properties
=(3)
5(1) = 5
(3 ∙2 ) ∙𝑥=3 ∙ (2 ∙𝑥 ) Associative Prop of Mult.
Symmetric Property
Multiplicative Identity
3. Three times the difference of 7 and x
3(7-x)
4. Twice the sum of 3 and x2(3 + x)
Modeling Words with an Algebraic Expression
5. for x = – 3, y =– 2 = = = =
Evaluating Algebraic Expressions
6. 35 – 8x = 3 – 8(x – 4)35 – 8x = 3 – 8x + 3235 – 8x = – 8x + 35 + 8x + 8x
35 = 35ALWAYS TRUE!!!
Infinite Solution!!
Solve a Multi-Step Equation
7. +3 +3
2x = 60 2 2x = 30
Solve a Multi-Step Equation
(5)(5)
Solve for x.8.
x(2 + 3y) = 6y2 + 3y 2 + 3y
Solve a Literal Equation
9. – 3x + 4 > 10
- 4 - 4- 3x > 6 - 3 -3
x < -2
Solve & Graph Inequalities
FLIP!!!
(2)(2)
10. -4x + 2 > - 22 and 6x – 7 > 47
-2 -2 +7 +7 -4x > -24 and 6x > 54
-4 -4 6 6x < 6 and x > 9
Not Possible!!No Solution
Solve & Graph Inequalities
FLIP!!!
11. 6 fewer than a number is at least 10
x – 6 10
12. Twice the difference of 3 and a number is no more than 15
Write an Inequality from a Sentence
13.
3x + 2 = 2 or 3x + 2 = - 23x = 0 3x = - 4x = 0 or x =
Solving an Absolute Value Equation
14. -72 +2 +2
-707 7
-10No Solution!
Solving an Absolute Value Inequalities
15. - 26 - 20
4 – x < 5 and 4 – x > - 5-x < 1 -x > -9x > -1 and x < 9 -1 < x < 9
Solving an Absolute Value Inequalities
16. -12All Real Numbers!!
Solving an Absolute Value Inequalities
3x + 1 = 2 or 3x + 1 = - 2
(greatOR)
3x + 1 2 or 3x + 1 < - 2
(less thAND)
3x + 1 2 and 3x + 1 > - 2
Remember! **********
GREATOR THAN NEGATIVE◦ Infinite solutions (all real numbers)
LESS THAN NEGATIVE◦ No solutions
Remember! **********
17.
* Know it’s Great“or” >
* Find average of endpoints
*Find how far endpts are from avg: 14
