Answer:
C
Step-by-step explanation:
its c because if we input the numbers into the slope formula y2 - y1 over x2 - x1 it equals -6 - 0 over 6 - 5
Answer:
Step-by-step explanation:
The difference is a2 - a1 = 31 - 24 = 7
n = 500
a500 = a1 + (500 - 1) * 7
a500 = 24 + 499 * 7
a500 = 24 + 3493
a500 = 3517
Answer:
![\#\text{ of 8-onion bags: }4,\\\#\text{ of 3-onion bags: }3](https://tex.z-dn.net/?f=%5C%23%5Ctext%7B%20of%208-onion%20bags%3A%20%7D4%2C%5C%5C%5C%23%5Ctext%7B%20of%203-onion%20bags%3A%20%7D3)
Step-by-step explanation:
Let
be the number of bags with 8 onions and let
be the number of bags with 3 onions. We have the following system of equations:
![\begin{cases}a+b=7,\\8a+3b=41\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7Da%2Bb%3D7%2C%5C%5C8a%2B3b%3D41%5Cend%7Bcases%7D)
Subtracting
from both sides of the first equation, we get
. Substitute this into the second equation:
![8(7-b)+3b=41,\\56-8b+3b=41,\\56-5b=41,\\-5b=-15,\\b=\boxed{3}](https://tex.z-dn.net/?f=8%287-b%29%2B3b%3D41%2C%5C%5C56-8b%2B3b%3D41%2C%5C%5C56-5b%3D41%2C%5C%5C-5b%3D-15%2C%5C%5Cb%3D%5Cboxed%7B3%7D)
Therefore, the number of 8-onion bags is:
![a=7-b,\\a=7-3,\\a=\boxed{4}](https://tex.z-dn.net/?f=a%3D7-b%2C%5C%5Ca%3D7-3%2C%5C%5Ca%3D%5Cboxed%7B4%7D)
Thus, the chef got 4 8-onion bags and 3 3-onion bags.
Explanation:
AB=7
AC=9
You are looking for R
7+9=16
So R is 16
