Answer:
Circumference = 10π
Step-by-step explanation:
First identify the circumference formula as such:
2πr (where r ⇒ radius, π ⇒ pi)
Knowing 2 times the radius (2r) in the formula can be rewritten as the diameter, the formula itself can be rewritten as:
πd (where d ⇒ diameter, π ⇒ pi)
If we know the diameter = 10 inches, substitute in the circumference formula πd to get:
π * 10 inches = 10 * π inches = 10π inches

Answer:
Step-by-step explanation:
(0, -3) not a solution
(2,1) solution
(3,-4) not a solution
(-5,7) solution
2x-8=5x+5
5x-2x=-8-5
3x=-13
x=-13/3,
or
x=-4 1/3
