Apilot is flying a crj-900 from phoenix, arizona, to louisville, kentucky. the aircraft cannot take off or land if the temperature on the field is not within its operating limitations. the aircraft cannot operate if the temperature is at or below −40° f, or at or above 118° f.

part a: write an inequality to represent the temperatures the pilot can take off and land in. (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 june 1990, the temperature in phoenix, arizona rose to 122° f. could the pilot have taken off on this day? why or why not? (4 points)

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
