Think back to the rock climbing activity you did in groups before winter break. If you didn't do it, click on the link on your Period's general page and look at it. How did you feel about solving differences with positive and negative rational numbers?
(Example: She climbed 5 feet and fell 3 feet. Her final elevation is 2 feet).

Rate on a scale from 1-5.
1= I had a lot of difficulty with the activity.
5=I felt confident about the activity.
Why? 2-5 sentences.

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

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'.

c) yes, because of asa or aas
