What is the domain of the relation {(3, 4), (4,3), (4,4), (5, 2)}?

{3,4,5}

Step-by-step explanation:

The domain is the set of all the values of x.

All the x values are 3, 4, and 5.

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:

i found two solutions,   n = 2 • ± √3 = ± 3.4641
