|
complementary angle
|
Two angles are Complementary when they add up to 90 degrees
|
|
|
diameter
|
A straight line going through the center of a circle connecting two points on the circumference.
|
|
|
equivalent equation
|
Equivalent Equations are the equations that have the same solution.
|
|
|
identity
|
An equation that is true no matter what values are chosen.
|
|
|
inconsistent equation
|
two or more equations that are impossible to solve based on using one set of values for the variables.
|
|
|
interval notation
|
a way of writing the set for an interval using theinterval's endpoints and [] or () around the endpoints depending on whither the endpoint is included or not respectively. The endpoints must be in increasing order.
|
|
|
linear equation
|
an equation between two variables that gives a straight line when plotted on a graph
|
|
|
linear inequality
|
aninequality which involves a linear function. Alinear inequality contains one of the symbols ofinequality: < is less than. > is greater than. ≤ is less than or equal to.
|
|
|
multiplication property of equality
|
states that if you multiply both sides of an equation by the same number, the sides remain equal (i.e.equality is preserved).
|
|
|
multiplicative inverse
|
one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2; the multiplicative inverse of 7 is 1/7
|
|
|
negative multiplication property of inequality
|
When we multiply both a and b by a positive number, the inequality stays the same. But when we multiply both a and b by a negativenumber, the inequality swaps over! Here are the rules: If a < b, and c is positive, then ac < bc.
|
|
|
quotient
|
a result obtained by dividing one quantity by another.
|
|
|
radius
|
a straight line from the center to the circumference of a circle or sphere.
|
|
|
solving
|
The process of finding the number or numbers that make an equation a true statement.
|
|
|
supplementary angle
|
Two Angles are Supplementary if they add up to 180 degrees.
