Answer:
(4,-4)
Step-by-step explanation:
The recursive rule is
![a_n=a_{n-1}+(-4)](https://tex.z-dn.net/?f=a_n%3Da_%7Bn-1%7D%2B%28-4%29)
.
The iterative rule is
![a_n=14-4n](https://tex.z-dn.net/?f=a_n%3D14-4n)
The recursive rule is given by the formula
![a_n=a_{n-1}+d](https://tex.z-dn.net/?f=a_n%3Da_%7Bn-1%7D%2Bd)
, where d is the common difference. Our common difference is -4, which gives us the recursive rule above.
The iterative rule begins with the formula
![a_n=a_1+d(n-1)](https://tex.z-dn.net/?f=a_n%3Da_1%2Bd%28n-1%29)
, where a₁ is the first term and d is the common difference. Our first term is 10 and our common difference is -4:
5(x+y)= 20+ 3x
5x+5y=20+3x
5x+5y-3x=20+3x-3x
2x+5y=20
2x+5y-2x=20-2x
5y=-2x+20
5y/5=-2x/5+20/5
y=-2/5x+4
ANSWER: y=-2/5x+4
