Cody looked at this graph of a circle. He drew the two vertical lines and said, “The graph is a function because these vertical lines do not intersect the graph more than once.”Which is the best explanation of why Cody’s reasoning is incorrect? A. A graph is a function if there are no vertical lines that intersect it. Therefore, Cody’s line on the left shows that this graph is not a function. B. A graph is not a function if you can draw a vertical line that does not intersect the graph. Therefore, Cody’s line on the right shows that this graph is not a function. C. A graph is not a function if any vertical line intersects it more than once. Cody’s lines do not intersect the graph more than once, but other vertical lines do. Therefore, this graph is not a function. D. A graph is not a function if more than one vertical line intersects the graph. Only one of Cody’s lines intersects the graph, but there are other vertical lines that do. Therefore, this graph is not a function.

Jack and Diane were saving money to go to a rock n roll concert. They need at least $750 in order to go if you count their gas, hotel, food, concert tickets, and souvenir money. Jack plays gigs at the local Tastee Freez and Diane car hops. Jack earns $50 per night that he plays, and Diane earns $25 each night she works. The number of nights Diane is scheduled to work is no more than four times the number of nights Jack is scheduled to play. Diane will work at least 10 times before the concert. Write a set of constraints to model the problem, with x representing the number of nights Jack worked and y representing the number of nights Diane worked.

The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5 x plus 10 y equals 800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total?
