|
coefficient
|
A number that is multiplied by a variable in an equation or an expression
Ex: 7a, 10x |
In 3x, the definition is the number 3 only
|
|
|
commutative property
|
changing the order of the values you are adding or muliplying (this does not change the sum or product)
Ex: 5+4 = 4+5 |
This is the property that says that 1+2 is the same as 2+1. This property starts with the letter "c"
|
|
|
congruent figures
|
figures that have the same size and shape
|
two identical squares are also two c_ _ _ _ _ _ _ _ squares
|
|
|
constant term
|
a number in an equation that is not multiplied by a variable
|
|
|
|
coordinate graph
|
a plane formed by two number lines that intersect at their zero points
|
This is what you put coordinate points on.
|
|
|
coordinate pair
|
an ordered pair of numbers used to locate a point on a coordinate grid
|
What is this called:
(2,3) or (5,6) |
|
|
dependent variable
|
one of two variables in a relationship. It's value depends on or is determined by the independent variable
|
In a graph, there are two variables.
For example: time and speed. This variable, speed, is the d______________ v______________ |
|
|
distributive property
|
when a number is multiplied by the sum of two other numbers, the first number can be handed out to both of those two numbers and multiplied by each of them seperately
Ex: a (b+c) = a(b) + a(c) |
What is this property called?
3(x+2) = 3x+6 |
|
|
equation
|
a rule containing variables that represents a mathematical relationship.
y = 3x+1 |
What is this called?
y = 3x+7 |
|
|
image
|
a point, line or figure that has been transformed to a new set of coordinates
|
|
|
|
independent variable
|
one of two variables in a relationship. Its value determines the value of the dependent variable
Example: With time and distance relationship, time is the independent variable. It is on the x-axis |
|
|
|
integers
|
the set of whole numbers and their opposites.
Example: 3, -3 5, -5 |
What is this called:
1, -1, 2, -2 |
|
|
line of reflection
|
a line across which an image is reflected
|
|
|
|
linear relationship
|
a relationship in which there is a constant rate of change between two variables.
y = 2x or a coordinate graph that shows a straight line |
|
|
|
order of operations
|
when expressions have more than one operation, we have to follow rules for the order: PEMDAS
Example: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction |
What is the system called that you use to answer the following:
3(5)-2+7/14 |
|
|
Range
|
the difference between the greatest and least values in a data set
Example: The range of the following: 1,2,2,3,4 is 4-1 = 3 |
You have a set of numbers...
You find the biggest number and the smallest number. The difference between the two is called: 1, 2, 3 , 7, 7, 8, 12 12 - 1 = 11 This is the: |
|
|
rate
|
a ratio that compares different kinds of units
Example: miles per gallon is an example of unit rate |
|
|
|
rational numbers
|
a number that can be expressed as the quotient of two integers, where the divisor is not zero
Example: 1/2, 0.79, 23 |
|
|
|
relationship
|
an assocation between two or more variables. A change in one affects the other.
Example: as time increases, distance increases |
|
|
|
similar figures
|
figures that have corresponding angles with equal measures and corresponding sides with proportional lengths
|
|
|
|
transformation
|
a change of position or size of a figure:
4 types: translations, reflections, rotations and dilations |
|
|
|
translation
|
a transformation that moves points in the same distance and in the same distance
|
|
|
|
x - axis
|
the horizontal number line that, together with the y-axis forms the coordinate graph
|
|
|
|
y-axis
|
the vertical number line that, together with the x-axis, forms the coordinate graph
|
|
