Una empresa de tv por cable actualmente presta servicio a 8000 familias cobra $50 por mes. una encuesta de marketing indica que cada reducción de $5 en el cobro mensual resultará en 1000 nuevos clientes. con r(x) denote el ingreso mensual total cuando el cobro mensual es en x dólares. determine la función de ingreso r, encuentre el valor de x que resulte en ele máximo ingreso mensual. ayuda por favooor.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
