What is the solution to the equation 2x+4-12-20?
X=0
x=1
X=2
X=9

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
