The number of coins in the first box was ![67\ coins](https://tex.z-dn.net/?f=67%5C%20coins)
The number of coins in the second box was ![83\ coins](https://tex.z-dn.net/?f=83%5C%20coins)
Finally
The number of coins in the first box is ![50\ coins](https://tex.z-dn.net/?f=50%5C%20coins)
The number of coins in the second box is ![100\ coins](https://tex.z-dn.net/?f=100%5C%20coins)
Step-by-step explanation:
Let
x-----> number of coins in the first box originally
y-----> number of coins in the second box originally
we know that
![x+y=150](https://tex.z-dn.net/?f=x%2By%3D150)
-----> equation A
-----> equation B
substitute equation A in equation B
![y+17=2x-34](https://tex.z-dn.net/?f=y%2B17%3D2x-34)
![y+17=2(150-y)-34](https://tex.z-dn.net/?f=y%2B17%3D2%28150-y%29-34)
![y+17=300-2y-34](https://tex.z-dn.net/?f=y%2B17%3D300-2y-34)
![y+2y=300-34-17](https://tex.z-dn.net/?f=y%2B2y%3D300-34-17)
![3y=249](https://tex.z-dn.net/?f=3y%3D249)
![y=83\ coins](https://tex.z-dn.net/?f=y%3D83%5C%20coins)
Find the value of x
![x=150-83=67\ coins](https://tex.z-dn.net/?f=x%3D150-83%3D67%5C%20coins)
therefore
Originally

The number of coins in the second box was ![83\ coins](https://tex.z-dn.net/?f=83%5C%20coins)
Finally
The number of coins in the first box is ![(67-17)=50\ coins](https://tex.z-dn.net/?f=%2867-17%29%3D50%5C%20coins)
The number of coins in the second box is ![(83+17)=100\ coins](https://tex.z-dn.net/?f=%2883%2B17%29%3D100%5C%20coins)

Answer:
Step-by-step explanation:
y = -14, m = -2, b = -2
-14 = -2(x) + -2
-14 = -2x + -2
-12 = -2x
Divide by -2.
x = 6
Your answer is 8/5
If you plug it in, you get:
8/(2+3)
Add the 2 and 3 and you’ll get
8/5
Answer:
{(-2, 8), (1,5), (4,2), (7, -1)} represents a linear function.
Step-by-step explanation:
In order to get from an x-value of -2 to 1 you add 3.
In order to get from a y-value of 8 to 5 you subtract 3.
This pattern is consistent with each coordinate in the ordered pair.
