What should allison do next to find the value of the expression?

a. remove 2 negative tiles
b. remove 3 negative tiles
c. add 2 negative tiles
d. add 7 negative tiles

A. remove 2 negative tiles

Step-by-step explanation:

-5 -(-2) is equal to -3. Two negatives make a positive, so this expression can be rewritten as -5 + 2.

To show this, you are "taking away" 2 tiles (-2) so the answer is to remove 2 negative tiles.

This corresponds with answer choice A. remove 2 negative tiles.

A. Remove 2 negative tiles.

Step-by-step explanation:

The given expression is -5 - (-2).

Allison begins with 5 negative tiles.

The expression says, we have to subtract -2 from - 5

So we have to get rid of -2 from -5.

Therefore, from 5 negative tiles, we have to get out 2 negative tiles.

When out 2 negative tiles, we will have 3 negative tiles.

The answer is A. Remove 2 negative tiles.

there are no short passages to look at

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'.
