During a recent housing slump, the median price of homes decreased in the united states. if james bought his house for $360,000 and the value 1 year later was $253,800, compute the percent decrease in the value of the house. if necessary, round to the nearest tenth of a percent.

Purchase price of the house = $360,000

Price of the house after 1 year = $253,800

Percent decrease in the value of the house = * 100

⇒ Percent decrease in the value of the house = * 100

⇒ Percent decrease in the value of the house = * 100

⇒ Percent decrease in the value of the house = 29.5%

Hence, the price of the house decreased by 29.5% over an year.

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'.
