Answer:
-4,5 / 5,3 . . .. ........
<span>24 cans costs £6
6/24 = 0.25 each can
5 * 0.25 = </span><span>£1.25
answer: </span>£1.25 for <span>5 cans</span>
X2+5x+y2-y=-2
X2+2*5x2+(5/2)^2-(5/2)^2+y2-2*y/2+(1/2)^2-(1/2)^2=-2
(x+5/2)^2+(y-1/2)^2-13/2=-2
(x+5/2)^2+(y-1/2)^2=9/2
So centre =(-5/2,1/2)
Radius=(9/2)^(1/2)
I really don’t understand this question. can you explain this in the comment so i can answer your
