(july 18) let a 1,2,3,4 and b 1.2,3,4.5) find a function t property or briefly explain why no such function exists 1. a function f: ab that is 1-1. 2. a function g: a-b that is onto 3. a function h: a a that is an equivalence relation

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

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:

thats one

step-by-step explanation:

answer is c

step-by-step explanation:

81/12=324/x

x=48
