An unknown number y is 15 more than an unknown number. The numbery is also x less than 8. The equations to find x andy are shown below.
y=x+ 15
y=-x+8
Which of the following statements is a correct step to find x and y? (4 points)
оа
Multiply the equations to eliminate y

Ob
Add the equations to
eliminate x.

Write the points where the graphs of the equations intersect the x-axis.

Write the points where the graphs of the equations intersect the y-axis.

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'.

just pick what you think i need more time let me know if this

step-by-step explanation:

hope i with whatever it is that you need! : )
