The benefit of these systems is that they might make a driver aware of an object ahead well before the driver could see it using just the headlights someone !

Night Vision System

Night Vision is based upon infrared technology and it uses infrared rays to locate any object present in a far distance from us during night or dark environment. Infrared rays are invisible to human eyes but there are some googles which if we wear can be able to see in dark. So wearing night vision googles a driver can become aware of an object ahead well before the driver could see it using car headlights.

10% of increase is the final answer! : )

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'.
