Answer:
No solutions.
Step-by-step explanation:
If you normalize the second one by dividing by 2, you get:
y = 5/2x+4.
Now you see that both have the same slope (5/2). They are parallel lines that never intersect.

Answer:
I don't know how to do this thing
Answer:
8 miles or 25.133 miles
Step-by-step explanation:
your radius is 4 miles.
The area of a circle is A=
Therefore, the area of this circle is , or 16
Half of this area, because what you're looking for is a semi-circle, is:
8 (exact) or 25.133 (rounded) miles.
