And can you give an explanation on how you got the answer too?

b.

Step-by-step explanation:

When you replace x in a parent function by x - h, the function shifts h units horizontally.

Here, x is replaced with x + 4.

x + 4 = x - (-4)

x - (4) = x - h, so h = -4.

The shift is 4 units to the left.

yeah and

step-by-step explanation:

you know what it isnt great cheating

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
