There is no specific answer because it is impossible to answer that question<span />
Answer:
The answer is the option D
and 
Step-by-step explanation:
we have


we know that
The solution of the system of equations is the intersection point both graphs
Using a graphing tool
see the attached figure
The solution are the points
and 
therefore
The solution of the equation
are

so
For 



For 


therefore
and
because the intersection points are common points for both graphs
3/8 cross multiply x/800 8x and 2400 divide both sides by 8 to get 300. 300 is the answer
Answer:

Step-by-step explanation:
Given that 
From the graph when 
Hence 
Now from the graph
