Two runners are saving money to attend a marathon. The
first runner has $112 in savings, received a $45 gift from a
friend, and will save $25 each month. The second runner
has $50 in savings and will save $60 each month
Which equation can be us
. months it will take for both
amount of money?
112 - 25m + 45 = 50 -
112 + 25 + 45m = 50m
112 + 25 – 45m = -50m
0 112 + 25m + 45 = 50 + 60

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?
