As shown in the graph, δghi ≅ δg'h'i', since this is a vertical shift, and δg'h'i' ≅ δg''h''i'', since this is a horizontal shift. we can also show that triangles ghi and g''h''i'' are congruent directly, by using the translation a) (x, y) → (x + 3, y - 4). b) (x, y) → (x - 3, y + 1). c) (x, y) → (x + 2, y + 2). d) (x, y) → (x + 4, y - 5).

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:

answer: 800
