Answer:
Infinitely many solutions (the lines are identical)
Step-by-step explanation:
Let's start by getting each equation into slope intercept form (y=mx+b)
-14x-14y=28
-14x-28=14y
-x-2=y
and
7x+7y= -14
7x+14= -7y
-x-2=y
We can see that these two lines are identical which means that there are an infinite amount of answers
Since there are 60 seconds in a minute multiply 8 by 60
The rate is 480 feet per minute.
If you add them all together, you'd get 157. Then you divide by 7 and you'd get 31.4
