I got a Guinness can whose temperature is 21^(circ)C. To enjoy it cold at the perfect temperature of 9^(circ) C, I set my refrigerator to 0^(circ)C. The temperature T(t) of the can at time t measured in seconds satisfies Newton's Cooling Law equation: [dT]/[dt] =-.0001 T. How long will it take for the can to cool off to 9^(circ) C?

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)
