Answer:
let the scone be x and the large coffees be y.
7x+4y=$25.76-----equ(I)
2x+5y=$14.92-----equ(2)
make x the subject of the formulae in equation(ii).
x=$14.92/2-5y
x=7.46-5y
Step-by-step explanation:
the answer is

The equation of a circle is written as ( x-h)^2 + (y-k)^2 = r^2
h and k is the center point of the circle and r is the radius.
In the given equation (x+3)^2 + (y-1)^2 = 81
h = -3
k = 1
r^2 = 81
Take the square root of both sides:
r = 9
The center is (-3,1) and the radius is 9
