The temperature of a liquid in an experiment changes by −10.4°F from the beginning of the experiment to the first check. After making some adjustments, the scientist checks the temperature again later and finds that it is 17.7°F, which is 13 what it was at the time of the first check. What was the initial temperature of the liquid?

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
