Answer: -2
Explanation: On the image we can see it goes down 4 units and right 2. Giving us the slope
Simplified that is -2 which is the slope of the line
Circular pen means you are going to use Area = Pi(r^2).
So 78.5 = pi(r^2). Divide by pi on both sides to get r^2 = 78.5/pi. Take the square root of that to get r or radius = approximately 4.99. If you need an exact answer then use
for the next part because you are not done yet.
Plug whatever R you use into the circumference formula of Circumference = 2(pi)(r).
If you use 4.99, you do 2(pi)(4.99) which is approximately 31.35. If you use the exact answer, you do 2(pi)(
) which gives you approximately 31.41.
Either way you'll need about 31 meters of chicken wire but the 31.40796 or ~31.41 is closer to the exact answer.

Answer:
The answer is B.
Step-by-step explanation:
Solve for x.
-5x + 5 160 - 10x
Add 10x to both sides, and subtract 5 from both sides.
5x 155
Now, divide by 5.
x 31 is the answer
