A sales team estimates that the number of new phones it will sell is a function of the price that it sets. It estimates that if it sets the price at x dollars, it will sell f(x)=6,102−9x phones. Therefore, the company's revenue is x⋅(6,102−9x). Find the price x that will maximize the company's revenue.

its a straight line parallel to the time axis

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
