I think the answer is C ( 11 )
Implicit defferentation
remember that dy/dx y= dy/dx
so
take derivitive of both sides

solve for

minus 2x both sides

divide both sides by 2y


when is the slope equal to

solve for





find where the circle and this line intersects
substitute

for y




times both sides by


sqrt both sides, take positive and negative roots
x=+/-10
sub back




the points are (10,-24) and (-10,24)
Construction IV is the most logical answer hope this helps :)
Answer: 
You need at least 125$ so it would be 5x is larger or equal to 125
When solving for x divide both sides by 5
125 / 5 = 25
x = 25
