the value of z varies inversely with the value of w. the constant of variation is 2/3. which are possible values for z and w? check all that apply.

a- z=4/3, w=1/2
b- z=2, w=3
c- z=1/3, w=2
d- z=4/15, w=5/2
e- z=7/2, w=1/3

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32
