Everyone loves baby pictures. imagine your typical 7-pound baby. this newborn baby should gain at least roughly 5 ounces per week after the fourth day of life until it is 6 months old. write a formula for the arithmetic sequence representing the baby’s weight from week 1 at 7 pounds until week 25.

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?
