square HIJK was reflected across the x-axis to create square H’I’J’K’. Which rule describes the reflection that was applied? (x, y) à (x, -y) (x, y) à (-y, x) (x, y) à (-x, y) (x, y) à (y, -x)

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

a is the right answer

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
