Part A: Quadrilateral ABCD is
rotated 90 degrees counterclockwise about the origin to form the quadrilateral A'B'C'D'. What are the signs of the coordinates (x, y) of point C'? 
A: (-4,4)
B: (3,6)
C: (3,2)
D: (-2,-2)

Part B:
Then quadrilateral A’B’C’D is reflected across the x-axis to form quadrilateral A’’B’’C’’D’’. What are the signs of the coordinates (x, y) of point B’’?

3,2

Step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
