In the following system of linear equations, state how to combine the two equations to obtain one equation with only one variable. 2x - 7y = 6 x + 3y = 2

Multiply the terms in the first equation by -3, the terms of the second equation by 7, and then add the equations.

Multiply the terms in the first equation by 3, the terms of the second equation by 7, and then add the equations.

Multiply the terms in the second equation by -2, and then add the equations.

Both b and c are correct.

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
