Answer:

y = 4

Step-by-step explanation:

Note that A and B have the same x-coordinate:  1.  This means that AB is a vertical line through x = 1.  The perpendicular bisector of AB must be a horizontal line situated halfway between y = 3 and y = 5.  Thus, it's just y = 4.

Review:  y = 4 bisects AB and represents a horizontal line.

Abigail is 8 years older than Cynthia. Twenty years ago Abigail was three times as old as Cynthia. How old is each now?
irina [24]
A - age of Abigail
C - age of Cynthia

A = C + 8

A - 20 = 3 (C - 20) 

A - 20 = 3C - 60  

C + 8 - 20 = 3C - 60

C - 12 = 3C - 60                A = C + 8

2C = 48                             A = 24 + 8 

C = 24 years                     A = 32 years
