Answer:
1. If j varies inversely as h, find k when j =4 and h=3.
j = k/h
4 = k/3
k = (4)(3)
k = 12
2. If x is inversely proportional to y, x=7 and y=8. Find k.
x = k/ y
7 = k/8
k = (7)(8)
k = 56
3. If s varies indirectly to t, s=11 and t=3. Find k.
s = k/t
11 = k/3
k = (11)(3)
k = 33
4. Supposed x varies inversely as y, Find k when x is -5 and y is 7.
x = k/y
-5 = k/7
k = (-5)(7)
k = -35
5. Supposed y varies inversely as z,Find k when y is 4 and y is 13.
y = k/z
4 = k/13
k = (4)(13)
k = 52
