Dee saves $20 a week for 10 weeks. during her 5-day vacation, she plans to spend $6.75 each day for snacks. which expression shows how much money she will have left?

$20 a week for 10 weeks is:

20*10 = $200

She spends $6.75 each day for 5 days:

6.75*5 = $33.75.

Lets subtract her spending from her savings to find out how much she has left:

$200-$33.75 = $166.25

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'.

i dont have an answer
