last saturday i went to a book store and bought the following items on pocket notebook which cost 23.75; a set of colored pens which cost 36.20 and a liquid eraser which cost 23.95 if she gave 100 - bill to the cashier, how much change did she receive? 1.what is asked in the problem? what are the given facts? 2.what operation to be used to solve the problem ? 3.solve 4.check and lookback​

The amount of change she received is

$16.1

Step-by-step explanation:

1.what is asked in the problem?

We are to find how much change she received

what are the given facts?

She bought:

notebook which cost 23.75; a set of colored pens which cost 36.20 and a liquid eraser which cost 23.95

She gave the cashier $100

2.what operation to be used to solve the problem ?

Addition and Subtraction operation

3.solve

= $100 - ($23.75 + $36.20 + $23.95)

= $100 - $83.9

= $16.1

The amount of change she received is

$16.1

no this is a nonlinear negative

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'.
