List the coordinates of FOUR vertices that create the feasible region on the graph. Submit your answer in the form of FOUR ordered Pairs (x, y)

(500,0) , (300,0), (200,200) and (300,200)

Step-by-step explanation:

The region of the graph we are concerned with is that small portion which is shaded.

We need the coordinates that bounds this portion of the graph.

These coordinates are four in number and they are as identified by noticing the four points that surround the portion then making tracings from these points to the x and y axes respectively.

We proceed as follows;

The four points we are looking at in no particular order are;

(500,0) , (300,0), (200,200) and (300,200)

The points having coordinates that have y = 0 are those that are domiciled on the x-axis

We have two of these points which are on the x-axis.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
