Please help its line segment

-9 3/4

Step-by-step explanation:

FG = GH

9x+15 = 5x+4

Subtract 5x from each side

9x+15-5x = 5x+4-5x

4x+15 = 4

Subtract 15 from each side

4x+15-15 = 4-15

4x = -11

Divide by 4

4x/4 = -11/4

x = -11/4

FG = 9x+15

FG = 9*(-11/4) +15

  = -99/4+15

    -99/4 + 60/4

   = -39/4

  = -9 3/4

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

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'.
