-7.5 times 1/3=-2.5
To take 1/3 of something, multiply the original by the fraction.
I'm going to assume that they are on parallel tracks, and not the same track.
60x=40(x+2)
60x=40x+80
20x=80
x=4
You can check the work I've provided by filling in the answer for x into the initial question.

The break even point is when profit is equal to zero, or in this case when p(x)=0
4x^2-28x+40=0
4(x^2-7x+10)=0
4(x^2-2x-5x+10)=0
4(x(x-2)-5(x-2))=0
4(x-5)(x-2)=0
So the break even points are when x=2 and 5, which is when 2000 and 5000 units are sold.
Answer:
(3,4) (4,3) (9,7)
Step-by-step explanation:
this represents a function because none of the x's in the x values repeat
