Verify if equation is a solution to the system of equations. equation y = –x + 1 is the ordered pair a solution to the system? yes, because there are infinite solutions to the system of equations. no, because substituting these values into the first equation creates a false statement. yes, because substituting these values into both equations forms two true statements. no, because substituting these values into the second equation forms a false statement.

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
