Calcula tres soluciones de las ecuaciones X + Y = 5 y X - Y = 0. A) Representa los tres pares de valores de cada una en unos ejes cartesianos y únelos b) ¿En qué punto se cortan las rectas que has obtenido en el apartado anterior? C) Resuelve el sistema formado por las dos ecuaciones. ¿cuál es su solución?

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

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

answer: x=3 and y=4
