first step to solving equations is to _____________when possible
distribute
nickname for slope
rise/run
rate of change
angles that are next to each other have what relationship?
they are supplementary, add to 180
formula for cylinder
pi x radius2 x height
reflect over x-axis means this value changes
y value
second step to solving equations
combine like terms
this slope type decreases from left to right
angels across from eachother have what relationship?
they are congruent/ equal
formula for cone
1/3 x pi x radius2 x height
each quadrant on the coordinate plane is worth this many degrees for rotations

the goal is to get variables on
one side/same side
this slope type is a vertical line
undefined
a big angle and small angle that are not next to each other, what is their relationship?
supplementary/add to 180
volume for sphere
