Answer: With what??? I don't see nun
The answer is 9. idk why you deleted my answer
The function represents the profit, and the company obviously wants to maximize it.
You can see that the profit increases until the parabola reaches its maximum.
The coordinate of the maximum look like (1.5, 90)
This means that, if the company invests 1.5 thousand dollars, the profit will be 90 thousand dollars, and this is the maximum profit the company can reach.
We will have the following:
First, we solve both equations for y, that is:
![6x-2y=4\Rightarrow-2y=-6x+4](https://tex.z-dn.net/?f=6x-2y%3D4%5CRightarrow-2y%3D-6x%2B4)
![\Rightarrow y=3x-2](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D3x-2)
&
![-9x+3y=12\Rightarrow3y=9x+12](https://tex.z-dn.net/?f=-9x%2B3y%3D12%5CRightarrow3y%3D9x%2B12)
![\Rightarrow y=3x+4](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D3x%2B4)
From this we can see that they are parallel lines, that do not share any common points, so there is no solution for the system.
