Answer:
A. China
Step-by-step explanation:
Solving the given system of equations we get solution set: {(4,0),(0,4)}
Option B is correct.
Step-by-step explanation:
We need to find the solution set of the following equations:
Let:
Finding value of x from eq(1) and putting in equation (2)
Putting values of y=4 and y=0 in equation(1), to find values of x:
Putting y=4
So, one solution is (0,4)
Putting y=0
So, other solution is: (4,0)
Hence Solving the given system of equations we get solution set: {(4,0),(0,4)}
Option B is correct.

Answer:
For this case we know that the total distance to travel is 325 mi. And we know that Aretha travels at the following velocity:
Then we can use the following definition:
Where D is the distance and V the velocity. And solving for t we got:
And replacing we got:
So then we can conclude that after 5 hours at this rate Aretha will arrive to home
