During swim practice, an olympic swimmer is required to complete three swimming intervals, in this order: warm-up freestyle, sprint freestyle, and cool-down breast stroke. after he completes each interval, he rests for three minutes.
sketch a graph that represents the swimmers’ interval times with respect to swimming speed. assign the x- and y-axes with appropriate labels. you may use description words instead of numbers to label the graph.

Jan and wayne went to the store to buy some groceries. jan bought 2 cans of corn beef hash and 3 cans of creamed chipped beef for $4.95. wayne bought 3 cans of corn beef hash and 2 cans of creamed chipped beef for $5.45. which assignment of variables can be used in finding the cost of each item in the word problem on the left? j = the number of cans jan bought w = the number of cans wayne bought h = the unit price of corn beef hash c = the unit price of creamed chipped beef j = the total cost of jan’s bill w = the total cost of wayne’s bill
