A truck driver is driving from Nome Alaska to death Valley California because he is traveling between locations with extreme temperatures he needs to check the weather consist continuously to make sure the gas in this truck remains in liquid form the gas he uses freezes at -40 F and evaporates at 140 F right and inequality to represent temperatures at which the gas in the truck will remain in liquid form also describe the graph on the any quality completely from Port a used term such as open close circle and port sharing directions explain with the solution to the new quality represents in January 1989 the temperature in Nome Alaska dropped -49F with the gas in the drivers truck

Answer 1

Full problem: A truck driver is driving from Nome, Alaska to Death Valley, California. Because he is traveling between locations with extreme temperatures, he needs to check the weather
continuously to make sure the gas in his truck remains in liquid form. The gas he uses froozos at -40°F and evaporates at 140° F.

Part A: Write an inequality to represent the temperatures at which the gas in the truck will remain in liquid form. (2 points)

Part B: Describe the graph of the inequality completely from Part A. Use terms such as open/closed circles and shading directions. Explain what the solutions to the inequality
represent. (4 points)

Part C: In January 1989, the temperature in Nomo, Alaska dropped to -49* F. Would the gas in the driver's truck have remained in liquid form so he could have driven on this
day? Why or why not? (4 points)

Answer 2

For part A) since the gas freezes at -40 and evaporates at 140 the temperature needs to be greater than -40 and less than 140. Let the temperature be some variable like t or x and write the appropriate inequality

Part B) the temperature has to be between -40 and 140 not including either -40 or 140 in the range. Would we use open circles or closed circles? Once you’ve determine that, think about where the graph would be shaded (to the left of the circles, to the right, in between?)

Part C) is -49F within the shaded area of the graph, if so this is a solution and the gas will remain liquid, and if not then this is not a solution and the gas will not remain liquid.
