Plzzz i need
a chemist is researching different sustainable fuel sources. she is currently working with benzene, which must be in liquid form for her to successfully conduct her research. the boiling point of benzene is 176* f, and the freezing point is 42* f.

part a write an inequality to represent the temperatures the benzene must stay between to ensure it remains liquid.

part b describe the graph of the inequality completely from part a. use terms such as open/close circles and shading directions. explain what the solution to the inequality represent.

part c in february, the buildings furnace broke and the temperature of the building fell to 20* f. would the chemist have been able to conduct her research with benzene on this day. why or why not?

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
