7th grade math help me pleaseee :)

A.  A + B (it'll be negative because they're both negative numbers and adding a negative is the same as subtracting a positive)

B. B - A ( It'll be positive because subtracting a negative is the same as adding a positive, and B is closer to 0 so it's a "bigger" number than A. so, adding A to B will make it positive)

Step-by-step explanation:

The explanations are in parenthesis to the right of the answer. they're kind of confusing, but the answers are correct.

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'.
