Which equation results from adding the equations in the system
×+6y=9
-×+2y=-15

x = 27/2 , y = -3/4

Step-by-step explanation:

x+6y=9

-x+2y=-15

0x +8y = -6

Divide each side by 8

8y/8 = -6/8

y = -3/4

Now find x

x +6y = 9

x +6(-3/4) =9

x - 9/3 = 9

Add 9/2 to each side

x = 9+9/2

x = 18/2 +9/2

x = 27/2

i can you with this sweetie!

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'.
