Zvaries directly with x and inversely with y. when x=6 and y=2, .z=15. write function that models variation. then, find z when x=4 and y=9. write answer in a/b form if necessary.

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
