Option B is correct.
Step-by-step explanation:
We need to identify which of the following equations has exactly one solution.
We will solve each equation to find the answer
A. 
Solving and finding value of x:
This equation has infinite number of solutions because both sides are equal to 0
B. 
Solving and finding value of x:
This equation has exactly one solution
C. 
This equation has no solution because both sides are not equal.
So, Option B is correct.

The answers to the various part as well as its reasons are given below
<h3 /><h3>Part A:</h3>
- The x-intercepts shows a zero profit.
- The maximum value of the graph tells or depict the maximum profit.
- The function is one that goes up or increases upward until it reach the vertex and then it falls or decreases after it.
- This implies that the profit goes up as it reaches the peak at the vertex and it goes down after the vertex up until it gets to zero.
- The profits are negative as seen on the left of the first zero and on the right of the second zero.
<h3>Part B:</h3>
An approximate average rate of change of the graph from x = 3 to x = 5, shows the reduction in profit from 3 to 5.
<h3>Part C:</h3>
Based on the above, the domain is one that is held back or constrained by x = 0 .
We are compelled at x = 6 due to the fact that we have to maneuver a negative profit.

(2x-5)-(3-9x)=2x-5-3+9x=11x-8
Answer:
45 degrees
Step-by-step explanation:
<em>the correct option is B...
6 . 4 - [4 + (9 - 3)]
= 6 . 4 - [4 + 6] BY SOLVING ( 9 - 3 )
= 6 . 4 - 10 BY SOLVING [ 4 + 6 ]
= 24 - 10
= 14 ANSWER ...:)
