2x + 1 = 9
x =4
5*10 + 8 -6/3
56
f(x) = -x + 3, find f(5)
-2
This segment goes across the entire circle from the middle
What is diameter?
This figure goes on forever in both directions in a straight path.
What is a line?
3x + 5 = 5x +1
x = 2
(9 + 12) - (15-12)^2
12
f(x) =3x^2 -7, find f(-1)
-4
This is the definition for the entire length around a circle.
What is circumference?
This figure extends in a straight path forever in one direction.
What is a ray?
