Advd player costs $250 and tv costs $600. with a 19% commission rate, how much
money does the sale clerk earn?

In this question, we're trying to find how much a sale clerk earns from a sale.

We know that the DVD player costs $250

We also know that the TV costs $600

The sales clerk has a 19% commission rate, this is the money that they make from the sale.

To find the money the sales clerk got from the sale, we have to add the total spending and multiply it by 0.19

250 + 600 = 850

850 · 0.19 = 161.5‬

This means that the sales clerk made $161.5‬0 in commission from the sale.

$161.50‬

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

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'.
