front 1 Integers | back 1 Counting numbers, their opposites, and zero. No decimals or fractions. (...-4, -3, -2, -1, 0, 1, 2, 3, 4...) |
front 2 Rational Number | back 2 A number that can be expressed as a fraction/ratio and has a decimal value that terminates or repeats. |
front 3 Irrational Number | back 3 A number that has a decimal value that does not repeat or terminate. The square root of a non-perfect square or the cube root of a non-perfect cube. |
front 4 Terminating Decimal | back 4 A decimal that stops or ends (0.125) |
front 5 Repeating Decimal | back 5 A decimal where a digit or a group of digits repeats forever. (0.77777777777....) |
front 6 Equation | back 6 A grouping of terms or values that use an equals sign to show an equal relationship. Statement in which two expressions are equal. 2x - 3 =7 |
front 7 Expression | back 7 A grouping of terms or values that DOES NOT have an equals sign 6x + 7 |
front 8 Solution | back 8 A value we can put in place of the variable that makes the equation true. 2 + x =4 2 + 2 =4 4=4 |
front 9 Variable | back 9 A letter or symbol that represents an unknown value (x) |
front 10 Coefficient | back 10 The number multiplied by a variable in a term. The number with the variable. 12x |
front 11 Constant | back 11 A value or number that never changes in an equation. A term that doesn't have a variable. 12x - 3 = 4 ^ ^ |
front 12 Distributive Property | back 12 Multiply a number outside parenthesis to both terms inside to get rid of parenthesis. 3(x - 7) |
front 13 Combining Like Terms | back 13 Simplifying the expression to lessen the number of terms 5x + 9 + 2x 5x +2x =7x 9=9 7x + 9 |
front 14 Opposite | back 14 Two numbers that are equal distance from zero (positive/negative) -4 and 4 |
front 15 Inverses | back 15 An operation that reveres/ undoes another (addition and subtraction) |
front 16 Step to Solving an Equation | back 16 1. Distribute 2. Combine Like Terms 3. Eliminate a variable from one side of the equation 4. Undo the Constant 5. Undo the Variable 6. Undo the Power- Square root or cube root |
front 17 Infinite Solution | back 17 An equation that has the same variable coefficient and constant on either side of the equal sign 3x + 4 = 3x + 4 |
front 18 One Solution | back 18 An equation that has one or different variable coefficient on each side of the equal sign -2x + 4 = 6x + 7 |
front 19 No Solution | back 19 An equation that has the same variable coefficients but different constants on either side of the equal sign 6x + 7 = 6x + 1 |
front 20 Pythagorean Theorem | back 20 In a right triangle, the hypotenuse squared is equal to the sum of the legs squared. Used to find the distance between two points and prove that a triangle is right or not. a^2 + b^2 = c^2 |
front 21 Hypotenuse | back 21 The longest side of a right triangle. Opposite the right triangle |
front 22 Leg | back 22 The two shorter sides of a right triangle. They form the right triangle |
front 23 Volume | back 23 Space occupied within a three- dimensional object |
front 24 Radius | back 24 Th distance from the center of a circle to any point on its edge |
front 25 Diameter | back 25 The distance from one point on a circle through the center to another point on the circle. |
