When you solve a linear equation how do you recognize if the equation has 1 solution no
solution, or infinite solution?

If you solve a linear equation you have two different lines.

Now with that being said the solutions are as follows;

One Solution: The slopes are different

No solution: The slopes are the same and the y intercepts are different

Infinite Solutions: The slopes are the same and the y intercepts are different

maybe i can

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
