El plan de un sitio de musica cuesta $9.99 por atomas $0.25 por canción descargada. Siun año pagaste $13.74
urtas canciones descargaste ese año?

Sí, descargaste Música ese año, descargaste 15 canciones.

Step-by-step explanation:

Así que la ecuación comenzaría por los planes de sitio que se restan del costo total de los pagos de años: $13.74 - $9.99 la respuesta es $3.75

luego dividir la respuesta que obtuvo por $0.25 con el fin de averiguar cuántas canciones que compró que es 15.

Espero que esto ayude

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'.
