Answer:
![f(-4) = \dfrac{1}{9}](https://tex.z-dn.net/?f=%20f%28-4%29%20%3D%20%5Cdfrac%7B1%7D%7B9%7D%20)
Step-by-step explanation:
![f(x) = 9(3)^x](https://tex.z-dn.net/?f=%20f%28x%29%20%3D%209%283%29%5Ex%20)
![f(-4) = 9(3)^{-4}](https://tex.z-dn.net/?f=%20f%28-4%29%20%3D%209%283%29%5E%7B-4%7D%20)
![f(-4) = 3^2 \cdot 3^{-4}](https://tex.z-dn.net/?f=%20f%28-4%29%20%3D%203%5E2%20%5Ccdot%203%5E%7B-4%7D%20)
![f(-4) = 3^{-2}](https://tex.z-dn.net/?f=%20f%28-4%29%20%3D%203%5E%7B-2%7D%20)
![f(-4) = \dfrac{1}{9}](https://tex.z-dn.net/?f=%20f%28-4%29%20%3D%20%5Cdfrac%7B1%7D%7B9%7D%20)
Answer:
C
Step-by-step explanation:
Because nintendo price=300$
He has 215$
1 chore he does=7$
Meaning if he did 10 chores he get's 70$ added so he did 10 now he has 285$ If he does 2 more chores that is 14$ more added.
So he now has 299$ so he done 12 chores and he needs 1 more dollar so if he did 1 more he gets 306$ and that was the least amount of chores he could do if he wanted 300$
And there's your answer
Hope this helps have a awesome day:)
I would say 95/6 because you multiply 5 and 15 and turn it into an improper fractions
