Iknow i have asked a lot of questions but i am in need of

the answer is 31/12

I hope this helps (;

First find common denominators. Multiply 4 to the second fraction's numerator and denominator.

(-9/3)(4/4) = -36/12

-5/12 - (-36/12) = Answer

Note that two negatives = one positive.

-5/12 + 36/12 = Answer

Combine the terms

31/12 = Answer

Change into mixed fraction

31/12 = 2 7/12

2 7/12 is your answer

hope this helps

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'.
