Answer:
the correct awnser is B
Step-by-step explanation:
It will lie in Quadrants I and IV, having center (5, 0) and radius 3. Complete the squares and get the equation in standard form, (x - 5)2 + y2 = 9.
4x+7y=4.88 -> mult by -3 -> -12x-21y=-14.64
12x+8y=7.88
-12x-21y=-14.64
Add the two above equations together, the y will be left:
-13y=-6.76
y=0.52 —> cost of each apple (plug back into one of original equations, I chose 4x+7y=4.88:
4x+7(0.52)=4.88
Solve for x.
x=0.31 —> cost of each orange
