The ECHS snack bar cooks and sells hamburgers and hot links during football
games. To stay in business, they must sell at least 10 hamburgers and 30 hot links.
They must also cook at most 40 hamburgers and 70 hot links. The snack bar can
not cook more than 90 items total. The profit on a hamburger and hot link are 85
cents and 63 cents, respectively. How many of each item should the snack bar sell
to maximize profit? What is the maximum profit?
In order to answer this question, you must define variables, write inequalities for
all the constraints, graph those inequalities to find the
feasible region, and write
the profit function, using it to find the maximum profit.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
