What steps need to be taken so that quadrilateral ABCD can be transformed to overlap quadrilateral A'B'C'D' so that their vertices match? O Rotate ABCD 90° clockwise about the origin, then translate it 8 units to the left.
O Translate ABCD 10 units to the left, then translate it 10 units down.
O Reflect ABCD about the y-axis, then rotate it 90° counter-clockwise about the origin.
O Translate ABCD 7 units down, then reflect it about the y-axis.

Reflect it across the Y axis then do a 90 degree CCW rotation.

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:

(x, y)→(x − 8, y − 7)

step-by-step explanation:
