375 / 15 = 25 ft per minute <== Rosa's tilling rate
Answer:
C (y=5x-7)
Step-by-step explanation:
First, you find the slope between the 2 points which is 5, then you use one of the points to form an equation.
You then find it's y=5x-7.
The equation to find percent error is:
percent error=(experimental-theoretical)/theoretical *100
So, (115-82.5)/82.5=0.393939*100
39.3939%, or 39.94%
Hope this helps!!

Answer:
![y = 23.75x + 76.24](https://tex.z-dn.net/?f=y%20%3D%2023.75x%20%20%2B%2076.24)
Step-by-step explanation:
We want to rewrite
![y = 99.99 + 23.75(x - 1)](https://tex.z-dn.net/?f=y%20%3D%2099.99%20%2B%2023.75%28x%20-%201%29)
in the form
![y = ax + b](https://tex.z-dn.net/?f=y%20%3D%20ax%20%2B%20b)
We expand to get:
![y = 99.99 + 23.75x - 23.75](https://tex.z-dn.net/?f=y%20%3D%2099.99%20%2B%2023.75x%20-%2023.75)
Regroup similar terms:
![y = 23.75x - 23.75 + 99.99](https://tex.z-dn.net/?f=y%20%3D%2023.75x%20-%2023.75%20%2B%2099.99)
Simplify:
![y = 23.75x + 76.24](https://tex.z-dn.net/?f=y%20%3D%2023.75x%20%20%2B%2076.24)
This is now of the form
![y = ax + b](https://tex.z-dn.net/?f=y%20%3D%20ax%20%2B%20b)
where a=23.75 and b=76.24
