Answer:
(x+4)^2 + (y+3)^2 = 5^2
Step-by-step explanation:
The equation of a circle is
(x-h)^2 + (y-k)^2 = r^2
now substitute the known values
(x+4)^2 + (y+3)^2 = 5^2
and theres your equation
Answer: the system has no solution
Step-by-step explanation: for a solution to occur the lines have to cross
21 times because you need 7/4=1 gallon and 3/4 just for one and 7x3 =21 so need 21/4
