| Question | Answer |
|---|---|
| Commutative Property of Addition | a + b + c = b + a + c |
| Commutative Property of Multiplication | abc = bac |
| Associative Property of Addition | (a + b) + c = a + (b + c) |
| Associative Property of Multiplication | (ab)c = a(bc) |
| Distributive Property | 4(x + 2) = 4x + 8 and (3 – x)2 = 6 – 2x |
| Substitution Property | if x = 10 then 5x = 50 |
| Identity Property of Addition | 5 + 0 = 5 |
| Identity Property of Multiplication | 7(1) = 7 |
| Inverse Property of Addition | 6 + (-6) = 0 |
| Inverse Property of Multiplication | 3(1/3) = 1 |
| Symmetric Property | if a = b then b = a |
| Addition and Multiplication Property of Equality | if a = b then a + 5 = b + 5 |
| Addition and Multiplication Property of Inequality | if a < b then 3a < 3b |
| Zero Product Property | If ab = 0 then a = 0 or b = 0 and (x-5)(x+2)=0 then x = 5 or x = -2 |
| Adjust | to change so as to fit additional information |
| Estimate | to calculate approximately |
| Volume | the region of space a three-dimensional object takes up |
| Surface Area | the sum of the areas of each of the sides of a three-dimensional object |
| Percent | number divided by the total, (times 100) move the decimal two places to the right |
| Coefficient of x | the slope when an equation is in slope-intercept form |
| Constant | the y-intercept when an equation is in slope-intercept form |
| Linear Inequality | has many solution, has no exponents |
| x-intercept | where the y coordinate equals 0, where the graph crosses the x axis |
| y-intercept | where the x coordinate equals 0, where the graph crosses the y axis |
| Solutions | points that satisfy an equation or inequality |
| Points on the Line | solutions for the equation |
| Pythagorean Theorem | a2 + b2 = c2 |
| Perimeter | the measure of the outside boundaries of a two-dimensional shape |
| Scale Factor | the ratio of corresponding sides of similar figures |
| Parallel Lines | lines that have the same slope |
| Perpendicular Lines | lines that have a negative reciprocal slope |
| Slope-Intercept Form | y = mx + b, where m is the slope and b is the y-intercept |
| Probability | favorable over total |
| Odds | favorable over unfavorable |
| Outliers | numbers that are out of range of the group |
| Measures of Central Tendency | mean, mode and median |
| Line of Best Fit | a line given from a scatter plot that estimates the equation |
| Prediction | to make an educated guess about a future value |
| Range | from data set, the difference of the highest number and the lowest number |
