A)
well, we know the elevator's rate is -20 f/s, ok, so every second, is dropping 20 feet, therefore, "y" is "distance from the ground floor", so when y = 0, meaning the distance to the ground floor is 0, so you ARE at the ground floor then.
and "x" is how many seconds you've been in the elevator.
now, she got in the elevator for 6 seconds, so, the elevator went down by 20 * 6, or 120 feet down, reason why the slope is negative, when she stopped, she was 350 feet away from the ground floor still though.
if the elevator went down 120 feet, and she's still 350 feet from the ground floor, that means she boarded the elevator at 120 + 350 feet, or 470 feet.

Answer:
Part a) The company can not build 12 chairs and 5 tables
Part b) The company can build 18 chairs and 3 tables
Part c) The company can build 12,13,14,15,16 or 17 chairs
Step-by-step explanation:
we know that
If a ordered pair is a solution, then the ordered pair must be belong to the feasible region of the graph
Part a) Can the company build 12 chairs and 5 tables?
In this problem we have the ordered pair A(12,5)
Plot and verify if the point belong to the feasible region of the graph
see the attached figure to better understand the problem
The point A is not on the feasible region
therefore
The company can not build 12 chairs and 5 tables
Part b) Can the company build 18 chairs and 3 tables?
In this problem we have the ordered pair B(18,3)
Plot and verify if the point belong to the feasible region of the graph
see the attached figure to better understand the problem
The point B is on the feasible region
therefore
The company can build 18 chairs and 3 tables
Part c) One week, the company decides to build 4 tables. how many chairs can the company build?
For y=4
Find the value of x in the graph
The solutions point for y=4 tables are
(12,4), (13,4),(14,4),(15,4),(16,4) and (17,4)
therefore
The company can build 12,13,14,15,16 or 17 chairs
From the given description it seems that the small shaded circle lies within the larger circle as shown in image below:
The probability that a point choosen at random lies within the shaded area = Area of shaded region / Total area of the bigger cricle
So,
Probability = 78.5/314 = 0.25
Thus there is 0.25 or 25% probability that the point chosen at random will lie inside the shaded region.
The probability that a point choosen at random lies within the shaded area = Area of shaded region / Total area of the bigger cricle
So,
Probability = 78.5/314 = 0.25
Thus there is 0.25 or 25% probability that the point chosen at random will lie inside the shaded region.
