Examine this system of equations with the procedure for which statements accurately describe this system and

using the linear combination method.

its solution? Check all that apply.

4x - 9y = 54

16x-36y=208

The linear combination method produced a true

statement

The solution to the system is (0, -8).

The lines are parallel.

There is one solution to the system.

There is no solution to the system.

There is no solution to the system

Step-by-step explanation:

To solve using linear combination method you have to first arrange the equation:

4x - 9y = 54                    (1)

16x-36y=208                 (2)

Secondly you analyze the coefficients and then multiply the equation by a number so that the coefficient are opposite:

Multiplying the first equation by -4 we get equation 3

-16x+36y=-208                (3)

16x-36y=208               (2)

Thirdly we add both equations to get:

Adding equations 2 and 3 gives

0 + 0 = 0

therefore, There is no solution to the system

uhhh idk u yolo?

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
