At a store, a hat has a regular price of a dollars. during a sale, the price of that hat is discounted by 20%.the expression 0.8x describes the discounted price in dollars of the hat?

Question?

Is the wording: price of "a" dollars, (in italics)?

If so, the equation would be:

0.8a

Otherwise, if "x" represents the regular price, then the equation would be:

0.8x

Step-by-step explanation:

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: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man
