Match the following. 1.the range and domain of P = {( x, y ) | y = 3}{2}
2.the domain set of C = {( 2, 5), (2, 6), (2, 7)}domain = {all real numbers}: range = {y: y = 3}
3.the range set of E = {(3, 3), (4, 4), (5, 5), (6, 6)}domain = range = {all real numbers}
4.the range and domain of F = {( x, y ) | x + y =10}{3, 4, 5, 6}

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

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:
