Section 1

(48 cards)

numerical expression

Front

consists of numbers and operations

Back

coordinate plane

Front

A plane that is divided into four regions by a horizontal line called the x-axis and a vertical line called the y-axis. aka "the Cartesian plane" after René Descartes

Back

linear equation

Front

an equation whose answers are ordered pairs (x,y) and whose answers graph a straight line

Back

additive inverse property

Front

The sum of a number and its opposite is zero.

Back

associative property of addition

Front

changing the grouping of terms will not change the sum, (a + b) + c = a + (b + c)

Back

y-intercept

Front

the point where a graph crosses the y-axis

Back

Slope Intercept Form

Front

y= mx + b where "m=slope" and "b=y-intercept"

Back

Inverse Operation

Front

operations that undo each other, such as addition and subtraction

Back

Slope Formula

Front

Slope=m= Y2 - Y1 / X2 - X1

Back

order of operations

Front

the order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction

Back

constant

Front

a term that has no variable and does not change

Back

domain

Front

the set of all the input (x-values) for a function

Back

Solve for a variable

Front

To get a variable alone on one side of an equation or inequality in order to solve the equation or inequality

Back

Inequality

Front

A statement that compares two quantities using <, >, ≤,≥, or ≠

Back

equation

Front

a mathematical sentence with an equal sign that shows that two expressions are equivalent

Back

variable expression

Front

consists of numbers, variables, and operations

Back

solving an equation

Front

finding all the solutions of an equation

Back

ordered pair

Front

A pair of numbers, (x, y), that indicate the position of a point on a coordinate plane.

Back

variable

Front

a letter used to represent one or more numbers

Back

ratio

Front

a comparison of two numbers by division

Back

integers

Front

Positive and Negative Whole Numbers and 0. Examples: .... -3, -2, -1, 0, 1, 2, 3.....(Does not include fractions or decimals)

Back

rational number

Front

A number that can be written as a/b where a and b are integers, but b is not equal to 0.

Back

associative property of multiplication

Front

changing the grouping of factors will not change the product, (ab)c = a(bc)

Back

additive identity property

Front

The sum of a number and zero is always that number.

Back

range

Front

the set of all the output (y-values) for a function

Back

input

Front

the x-value in a function

Back

x-intercept

Front

the point where a graph crosses the x-axis

Back

reciprocal

Front

one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2

Back

Equivalent Equations

Front

equations that have the same solution

Back

perimeter

Front

The sum of the lengths of the sides of a polygon

Back

function

Front

a relation that assigns exactly one output value for each input value

Back

area

Front

the number of square units needed to cover a flat surface

Back

commutative property of multiplication

Front

the order of the factors does not change the product a x b = b x a

Back

terms

Front

in an expression are separated by addition and subtraction signs

Back

slope

Front

the steepness of a line on a graph, rise over run

Back

evaluate

Front

to find the value of an expression

Back

commutative property of addition

Front

In a sum, you can add terms in any order, a + b = b + a

Back

rate

Front

a ratio that compares two quantities measured in different units

Back

irrational number

Front

a number that can not be written a/b

Back

coefficient

Front

number in front of a variable

Back

quadrant

Front

one of four sections into which the coordinate plane is divided

Back

like terms

Front

terms that have identical variable parts raised to the same power

Back

output

Front

the y-value in a function

Back

base

Front

is the number that is repeatedly multiplied in a power

Back

multiplication identity property

Front

The product of any number and one is that number.

Back

exponent

Front

a mathematical notation indicating the number of times a quantity is multiplied by itself

Back

power

Front

is a number made of repeated factors

Back

distributive property

Front

a(b + c) = ab + ac an + ac = a(b+ c)

Back
