Linear Systems
A linear system consists of
2 or more linear equations
You can expand a polynomial expression using this acronym
F.O.I.L
monomials consist of this many terms
1
The zero of a parabola
Where the graph crosses the x-axis
The Sine Ratio
Sin A=opp / hyp
Parallel lines have this many solutions (Point of intersection)
None
True or false
The first thing you do to solve an expression is expanding
False
The first thing you do is common factor
Factoring by grouping
The vertex is also called
The max/min value
the Greek symbol used to represent an unknown angle
Theta
The 3 ways to solve a linear system
Graphing, elimination and substitution
What order do you expand when using F.O.I.L.
First, outer, inner, last
To solve a hard trinomial, you have to do this type of factoring
Decomposition
If the y-value is negative, then the parabola will open
Up
All 3 sides are given and when you have a contained angle
Let statements
when something has an exponent of 0, it will always equally this
3 steps to squareing a binomial
first - square first term
middle - multiply the two terms and double it
last - square last term
The Axis of symmetry
A vertical line that divides the parabola in half
Ratios of corresponding sides
AB / DE = BC / EF = CA / FE
Formula for distance problems
d
s t
when solving an easy trinomial, use this method
Sum and product
This is factoring's 'opposite'
Expanding
When a 'k' value is subtracted to y=x^2, the parabola will shift..
The equation used to find a missing side if 2 are given
Pythagorean Theorem
a2 + b2 = c2
