A water tank already contains 55 gallons of water when someone begins to fill it. Water flows into the tank at a rate of 9 gallons per minute. Write a linear equation to model this
situation. Find the volume of water in the tank 30 minutes after someone begins to fill the
tank.

Someone me! if you’re smart you can solve this!

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?

Iknow the answer but the calculator doesn't seem to give the right one
