y=mx+b

Quadratic Formula

Holes in a rational Equation

Vertex form of a Parabala

Slope intercept form where m= slope and b= y-intercept

created by binomials in a rational function canceling out

y=a(x-h)^2+k, Vertex is (h,k)

y=mx+b

Slope intercept form where m= slope and b= y-intercept

Quadratic Formula

Percent

Percent Increase

Percent Decrease

common multiple of 2 numbers

part = percent X whole

Amount of Increase/Original Whole X 100%

amount of decrease/original whole X 100%

prime factor both numbers; multiply each factor the greatest n…

area of a circle

area of a parallelogram

circumference

cosine

A = pi times radius squared

A = base x height

C=π2r or diameter x pi, where diameter = 2 times the radius

Cosine = adjacent/hypotenuse. Remember CAH.
