1.
absolute value: The distance a number is from zero on a number line
2.
associative property: Changing the grouping of numbers will NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication
3.
base: the number or variable that is used as a factor in repeated multiplication
4.
base number: the number you are comparing to
5.
coefficients: number being multiplied by the variable
6.
commutative property: The order of two numbers may be switched around and the answer is the same.
7.
consecutive integer: numbers that increase by 1
8.
corresponding triangle: same position. same shape
9.
cross product property: The product of the extremes equals the product of the means
10.
direct variation: an equation of the form y=kx, where k does not equal 0. k=m
11.
domain: input
12.
equation: a statement formed when an equal sign is placed between two expressions
13.
formula: an algebraic equation that relates two or more real life quantities
14.
function: a rule that establishes a relationship between an input and output
15.
function notation: to write a rule in function notation, you use the symbol f(x) in place of y
16.
Identity property: The sum of 0 and any number is the number. The product of 1 and any number is the number.
17.
like terms: Expressions that contain the same variables to the same power
18.
linear: variable raised to the first power (not including pi or absolute value
19.
matrix: a rectangular array of elements (or entries) set out by rows and columns
20.
open sentence: an equation with one or more variables
21.
point slope form: y-y1 = m(x-x1), where m is the slope and (x1,y1) is the point the line is passing through.
22.
Power/exponent: the number or variable representing the number of times the base is used as a factor
23.
Property of zero: When multipling a number by zero, you product is always going to be zero.
24.
proportion: an equation that states two ratios are equal
25.
range: output
26.
real numbers: numbers that are positive, negative, and zero
27.
reciprocal property: if two ratios are equal, then their reciprocals are also equal
28.
relation: the same thing as a function, except the input can have more than one output.
29.
round- off error: the error produced when a decimal result is rounded in order to provide a meaningful answer.
30.
simple interest: The amount of interest based on a principal amount and not on earned interest. I=PRT
31.
simplify: to write an expression in a simpler form
32.
slope: rise/run. y2-y1/x2-x1. a measure of steepness of a line
33.
slope intercept form: y=mx+b, where m is the slope and b is the y-intercept of the line.
34.
solution of an equation: a # that produces a true statement when it is substituted for the variable in the equation
35.
term: seperated by a + or a -
36.
variable: a letter that represents one or more numbers
37.
variable expression: consists of numbers, variables, and operations (no equal sign)
38.
velocity: the speed and direction of a moving object
39.
vertical line test: A test used to determine whether a relation is a function by checking if a vertical line touches 2 or more points on the graph of a relation
40.
x- intercept: x coordinate of a point where a graph crosses the x axis/ y coordinate of this point is zero
41.
y- intercept: where the line crosses the y axis. x coordinate is zero
