Carly conducts a chemistry demonstration for her project. She decreases the temperature of two liquids at different but constant rates. This table shows the temperature of the liquids as they cool. Write a system of equations to represent Liquid A Ana Liquid B in Carly’s demonstration. Let x represent the time and y represent the temperature of the liquid.
