Term
the natural numbers AND 0, ex: 0,1,2,3...
Definition
whole numbers
Term
all the numbers that can be written as quotients of integers
Definition
rational numbers
Term
all the numkbers that CANNOT be written as quotients of integers
Definition
irrational numbers
Term
The natural numbers, zero, and the negative numbers.
Definition
Integers
Term
Order of operations (PEMDAS)
Definition
Parentheses, Exponents, Multiplication, Division, addition, subtraction
Term
A math sentance that compares the values of 2 expressions using an inequality symbol.
Definition
inequality
Term
a pair of inequalities joined by AND or OR
Definition
compound inequality
Term
the distance from zero on a number line
Definition
absolute value
Term
a solution of an equation that is NOT a solution (oh, THAT makes sense...not)
Definition
Extraneous Solution
Term
A set of pairs that have input and output values
Definition
Relation
Term
The set of all inputs, or x coordinates, of the ordered pairs
Definition
Domain
Term
the set of all outputs, or y values, of the ordered pairz
Definition
range
Term
a relation in which each element of the domain is paired with exactly one element in the range
Definition
Function
Term
an equation of the form y=!mx+h!+K
Definition
absolute value function
Term
the point where a function reaches a maximum or minimum
Definition
vertex
Term
a system that has one unique solution and intersecting lines
Definition
independent
Term
a system that has no solutions, parallel lines
Definition
inconsistent system
Term
a system that has many solutions, coinciding lines
Definition
dependent system
Term
what would you do in a problem like this:
4-4x _>36 (greater than or equal to)
Definition
Solve it like you would a normal algebraic problem, subtract 4 from each side then divide. When shading on the line, use a closed dot and shade to the right.
Term
When solving an inequality and graphing the solution (on a line) how do you know when to use a closed dot and when to use an open one?
Definition
closed dot= equal to
open dot = normal
Term
What do you do when you have a compound inequality?
Definition
Solve each equation on the side of the Or and then graph
Term
how can you tell if a graphing the solution on a line problem is and or or?
Definition
Greater than = Or (greatOR than)
Less than= and (Less thAN-D)
Term
what do you do with an AND problem?
Definition
have one equation be normal and have one where the number after the inequality is the opposite of what the normal one was (pos. or neg.)
Term
How do you know if a relation is a function or not?
Definition
Its not if it touches more than one point on a line, or if it has two repeating x values
Term
what is the slope?
Definition
the thing with the x
Term
what would you do in a problem like this? 2x-6y=18
Definition
divide each number by 18 to get x and y
Term
how would you find the vertex?
Definition
set what is in the absolute value symbols to 0
Term
how do you graph inequalities?
Definition
straight up graph them. Then look at the symbol when drawing the line:

< > is dotted line, equal to is solid

Shade up if its greater than, down if its less thannn
Term
Graph the absolute value inequality?
Definition
It will be a "V" shape and shaded.
greater than shade up
less than shade down
Term
solve each system by graphing?
Definition
Just plot the points and the point of intersection is your answer.
Term
inequality and real graphing means what?
Definition
you have to shade somewhere
