Answer:
The equations represent circles that result in the same graph.
Step-by-step explanation:
we have

Divide by -10 both sides
-----> equation A
This is the equation of a circle centered at origin with radius 
and
Divide by 5 both sides
-----> equation B
This is the equation of a circle centered at origin with radius 
equation A and equation B are equal
therefore
The system has infinite solutions, because the equations represent circles that result in the same graph.
Answer:
it is possible to get something rational.
Step-by-step explanation:
This can't really be explained.
B would have to equal 9 and a should equal -2 to get 0
It should be 4 qt + 1 qt is 1 gallon, I think
