7a-5b=28

A (-2,-3)

B (0,4)

C (4,0)

D (-3,-2)

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
