dependent variable
the outcome factor; the variable that may change in response to manipulations of the independent variable
opposites
two numbers that are the same distance from zero on a number line, but are in opposite directions. (-2 and 2)
base
the number or expression that is used as a factor in a repeated multiplication
rate
A ratio that compares two quantities measured in different units
integers
Whole numbers and their opposites
variable
a symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity
isoceles triangle
a triangle that has at least 2 congruent sides
exponent
a mathematical notation indicating the number of times a quantity is multiplied by itself
independent variable
The experimental factor that is manipulated; the variable whose effect is being studied.
inverse operations
operations that undo each other
coefficient
the numerical factor when a term has a variable.
rate of change
the relationship between two quantities that are changing, this is also slope
range
set of all of the possible y-values. OTPUTS
real numbers
the set of all numbers including rational and irrational numbers.
arithmetic sequence
adding a fixed number to each previous term
solution of an inequality
a number that produces a true statement when it is substituted for the variable in the inequality
common difference
the fixed number added to each previous term
sequence
number pattern
compound inequality
Two or more inequalities joined together by "and" or "or"
coordinate plane
A plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis
solution
a statement that solves a problem or explains how to solve the problem
natural numbers
The set of numbers 1, 2, 3, 4, ... Also called counting numbers.
reciprocals
Two numbers whose product is 1, such as 3/4 and 4/3
expression
a mathematical phrase that contains operations, numbers, and/or variables
function
a relation where each number in the domain is paired with exactly one number in the range.
quadrants
the four regions into which the x-axis and the y-axis that separate the coordinate plane.
domain
set of all of the possible x-values. INPUTS
prime
a number that has no factor but itself and 1
term
a number, a variable, or the product of a number and a variable
equation
a mathematical sentence with an equal sign
composite numbers
a whole number greater than 1 that has more than two factors
scalene triangle
a triangle with no two sides of equal length
like terms
terms with exactly the same variable factors in a variable expression
evaluate
substituting a given number for each variable
whole number
The set of numbers 0, 1, 2, 3, 4,....
function notation
to write a rule in function notation, you use the symbol f(x) in place of y
simplify
to write an expression in a simpler form
consecutive integers
integers that increase or decrease incrementally by 1
constant
a quantity that does not vary
y intercept
where the graph crosses the y axis
proportion
an equation that states that two ratios are equal
relation
A set of ordered pairs
factors
Numbers that are multiplied together to get a product
inequality
A statement that compares two quantities using <, >, ≤,≥, or ≠
direct variation
an equation of the form y=kx, where k does not equal 0
subtraction
adding the opposite
constant of variation
what the k is in the equation y = kx. Like the slope or rate of change
linear equation
an equation whose graph is a line
equilateral triangle
a triangle with three congruent sides
ratio
a comparison of two numbers by division
