Consider the parabola with a focus at the point (0,7) and directrix y = 1. Which two equations can be used to correctly relate the distances from the
focus and the directrix to any point (x, y) on the parabola?
A. a = y - 1; a = V(X +
+0)2 + (y + 7)2
O B. a = 1 = y; 2 = V(x+0)2 + (y - 7y?
O C. a= y-t a = (x+0)2 + (y - 7)?
O D. a = 1- y, a = (x+0)2 + (y + 7)?

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

answer: you need to organize this better it does not make sense.
