I believe the answer is c
Answer:
s = -35/6
Step-by-step explanation:
Let's evaluate your equation:
-6s = 35 <---- In order to evaluate this equation we must divide.
--------------
-6 -6
s = -35/6 <--- Final answer :D
I hope this helps :)
Slope is m given the general formula y=mx+b.
For this equation slope is -2
Answer:
Robert would have needed 259 point to increase his average to 211.
Step-by-step explanation:
Averages are described by the following equations:
Initial average:
![\frac{x}{n} = 205](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bn%7D%20%3D%20205)
![x = 205\cdot n](https://tex.z-dn.net/?f=x%20%3D%20205%5Ccdot%20n)
Real average:
![\frac{x+241}{n+1} = 209](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B241%7D%7Bn%2B1%7D%20%3D%20209)
![x + 241 = 209\cdot n + 209](https://tex.z-dn.net/?f=x%20%2B%20241%20%3D%20209%5Ccdot%20n%20%2B%20209)
![x = 209\cdot n - 32](https://tex.z-dn.net/?f=x%20%3D%20209%5Ccdot%20n%20-%2032)
![205\cdot n = 209\cdot n - 32](https://tex.z-dn.net/?f=205%5Ccdot%20n%20%3D%20209%5Ccdot%20n%20-%2032)
![4\cdot n = 32](https://tex.z-dn.net/?f=4%5Ccdot%20n%20%3D%2032)
![n = 8](https://tex.z-dn.net/?f=n%20%3D%208)
![x = 205\cdot (8)](https://tex.z-dn.net/?f=x%20%3D%20205%5Ccdot%20%288%29)
![x = 1640](https://tex.z-dn.net/?f=x%20%3D%201640)
Expected average:
![\frac{x+y}{n+1} = 211](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2By%7D%7Bn%2B1%7D%20%3D%20211)
![x + y = 211\cdot n+211](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%20211%5Ccdot%20n%2B211)
![y = 211\cdot n + 211 - x](https://tex.z-dn.net/?f=y%20%3D%20211%5Ccdot%20n%20%2B%20211%20-%20x)
![y = 211\cdot (8) + 211 - 1640](https://tex.z-dn.net/?f=y%20%3D%20211%5Ccdot%20%288%29%20%2B%20211%20-%201640)
![y = 259](https://tex.z-dn.net/?f=y%20%3D%20259)
Robert would have needed 259 point to increase his average to 211.
It depends how fast the snail goes.
