Step-by-step explanation:
2) Slope can be written as rise over run:
- rise: add to the y-value
- run: add to the x-value

3) Slope formula is: 

4) Average rate of change is the slope of the given interval:
a) when x = 0, y = 0 and when x = 1, y = -3

b) when x = -2, y = 0 and when x = -1, y = 3

c) when x = 0, y = 0 and when x = 2, y = 0

Answer:
Perimeter of figure = 36.3
Step-by-step explanation:
We'll begin by calculating the perimeter of the rectangle. This can be obtained as follow:
Length (L) = 9
Width (W = 4
Perimeter of rectangle (Pᵣ) =?
Pᵣ = 2(L + W)
Pᵣ = 2(9 + 4)
Pᵣ = 2(13)
Pᵣ = 26
Next, we shall determine the perimeter of semi circle. This can be obtained as follow:
Diameter (d) = 4
Pi (π) = 3.14
Perimeter of semi circle (Pₛ) =?
Pₛ = ½(πd) + d
Pₛ = ½(3.14 × 4) + 4
Pₛ = ½(12.56) + 4
Pₛ = 6.28 + 4
Pₛ = 10.28
Finally, we shall determine the perimeter of the figure. This can be obtained as follow:
Perimeter of rectangle (Pᵣ) = 26
Perimeter of semi circle (Pₛ) = 10.28
Perimeter of figure =?
Perimeter of figure = Pᵣ + Pₛ
Perimeter of figure = 26 + 10.28
Perimeter of figure = 36.28 ≈ 36.3
Answer: 3/2
Step-by-step explanation: Find the Rise over run. Easy as that, find two points on the line and see how many times it rises and how many times it runs.
The pair of points defines a line with a slope of -1 is C. (10,3) and (15,-2)
answer. 137.5 degrees
Step-by-step explanation: 135+140=275/2=137.5
