10.
rectangle efgh is graphed on a coordinate plane with vertices at
e(-3,5), f(6,2), g(4,-4), and h(-5, -1).
a. find the slopes of eagh side.
b. what do you notice about the slopes of opposite sides?
c. what do you notice about the slopes of adjacent sides?

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:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

$205,000 here you go i had to guess it but i got it correct so yeah
