The function a(b) relates the area of a trapezoid with a given height of 10 and one base length of 7 with the length of its other base.
It takes as input the other base value, and returns as output the area of the
trapezoid.
a(b) = 10.57
Which equation below represents the inverse function b(a), which takes the
trapezoid's area as input and returns as output the length of the other base?
O A. b(a) = +7
O B. (a) - 9+5
O c. b(a) = -
- 5
O D. b(a) 6-7

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: i guess 105 degrees?
