Answer:
![\boxed{y\leq 6}](https://tex.z-dn.net/?f=%5Cboxed%7By%5Cleq%206%7D)
Step-by-step explanation:
![y-8 \leq -2](https://tex.z-dn.net/?f=y-8%20%5Cleq%20-2)
Adding 2 to both sides
![y \leq -2+8](https://tex.z-dn.net/?f=y%20%5Cleq%20-2%2B8)
![y \leq 6](https://tex.z-dn.net/?f=y%20%5Cleq%206)
5 hours of free time a day*7 days a week = 35 hours of free time each week.
(8/35)*100 = % of time on internet per week (approx. 23%)
(10/35)*100 = % of time playing video games per week (approx. 29%)
First find the determinate
![\frac{1}{determinate} \left[\begin{array}{ccc}d&-b\\-c&a\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bdeterminate%7D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dd%26-b%5C%5C-c%26a%5Cend%7Barray%7D%5Cright%5D)
which is ad-bc
then use this to find the inverse
