With my algebra homework.

1.) what is the wuotient in simplified form? state any restrictions on the variable. (x^2-16/x^2+5x+6) / (x^2+5x+4/x^2-2x-8)

2.) simplify the sum
(7/a+8) + (7/a^2-64)

3.) simplify the difference
(a^2-2a-3/a^2-9a+18) - (a^2-5a-6/a^2+9a+8)

4.) simplify the complex fraction

(4/x+3) / ((1/x)+3)

5.) solve the equation. check the solution

(-2/x+4)=(4/x+3)

* i have been trying to figure these out all weekend and i can't. .

its definatley   this on your answer choice?

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'.
