Michael had $550 in his savings account. he took out $30.75 every month for one year. what is the net change in michael’s account balance following these withdrawals?

369 Has been taken out in total. He had 550 in his savings, so 550 - 369 is 181. He 181 USD left, and the net change is -$369 USD.

I'm not sure why this question has been up since 2016 but here's your answer...

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'.
