Iwill mark as brainy and give you 20 points ! 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 freezes 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 nome, 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:

a]

-40f < gas < 140f is the inequality expressing the state of the gas between -40f and 140

b]

the inequality would have open circles at the extreme points on the left and right ends of the inequality.

c]

well he would be a fool to try. it might last and it might not. in remote areas outside the cities [nome], the wilderness is a very cruel place. the chances of survival become very small even with good communication systems and warm clothing. it is not only the gas that is affected, it is the wheels and the engine and transmissions. i taught up there and we cancelled at -40o. there were no exceptions. the school buses simply did not run. it wasn't worth the risk

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
