X-2y = 3
-2y=3-x move the x over to the other side
-y=3/2 -1/2x divide both sides by 2
y=1/2x - 3/2 divide both sides by -1
The exponent indicates how many times the number is used as a factor
L x w x h = volume
volume = 5 x 5 x 5 = 125 cm ^ 3
F(x) means "function of" and x represents the day number, example: day 6 would be f(6)=(20×6)+95
