Which is the best step to do next to solve the equation by
completing the square?
The first few steps in solving the quadratic equation 9x2 +
49x = 22 - 5x by completing the square are shown.
9x2 + 49x = 22 - 5x
9x2 + 54x = 22
90x2 + 6x) = 22
9(x2 + 6x + 3) = 25
9(x2 + 6x + 3) = 49
90x2 + 6x + 9) = 31
9(x2 + 6x + 9) = 103

the answer

b. they are parallel and will never intersect.

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'.
