Algebra 1, Unit 1 Equations and Inequalities
Closed Circle or Closed Point
INCLUDES the number circled
Identity
In math it is an equality that holds true no matter what value is chosen for the variable
One-Variable
In math, we are referring to an equation that has only one variable
Equivalent Inequalities
Inequalities that have the same solution
Perimeter
The total distance around the edge of a shape; found by adding up all the sides
No Solution (for one equation or inequality)
There is no possible number that will make the equation or inequality true
Zero Pair
Two expressions that equal zero when combined
Equivalent Equations
Two or more equations with the same solution
Not Equal To
Value is equal to every number except the given value
Greater Than or Equal To
Value that is "at least" as big as another value or more; "No Less Than;" "Minimum;" Shade Right; Closed Circle
Less Than or Equal To
Value that is "at most" as big as another value or less;"No More Than;" "Maximum;" Shade Left; Closed Circle
Greater Than
Value that is "bigger than" another value; "More than;" Shade Right; Open Circle
Less Than
Value that is "smaller than" another value; "Fewer than"; Shade Left; Open Circle
Isolate
to separate from others; in math, it's getting a variable by itself on one side (left side) of an equation
Formula
A fact or a rule written with mathematical symbols; it usually connects two or more terms with an equal sign "="; when you know the value of one or more variable(s), you can find the value of the remaining variable using the formula
Equation
A mathematical sentence stating two expressions are equal "="
Inequality
A mathematical sentence that contains less than, greater than, less than or equal to, greater than or equal to, or not equal (<, >, ≤,≥, or ≠)
Literal Equation
An equation involving two or more variables
Infinite Solutions (for one equation or inequality)
Any real number can make the equation or inequality true
Distributing & Combining Like Terms
DCVAM ("Don't Call Vampires After Midnight"); D-Distributive Property, C-Combine Like Terms, V-Variables on Left Side, A-Add or Subtract, M-Multiply or Divide
Open Circle or Open Point
Does NOT include the number circled
Inverse Operations
Operations that undo each other: addition and subtraction, or multiplication and division.
Solving (for an equation with one variable)
The mathematical process of finding all the numbers for a variable that make an equation true.
