Which points define the solution set of this linear-quadratic system of equations

At point C (-0.5,2)

At point E (1,5)

Step-by-step explanation:

The points that defines the linear quadratic equation system is as follows:

As we can see that the point E and Point C are the solutions set that have an intersections between the parabola i.e. blue and the red line also they are on the both curves at the same time. In addition to this, their coordinates satisfy the both equations in the similar time

Hence, the same is to be considered

the y will be in still but your answer will be y x 3

jk: )

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
