Question 933868: 1) The pair of points is on the graph of an inverse variation. Find the missing value.
(14, 8) and (x, 7)
No solution
16
12.25
4
2)Suppose y varies inversely with x. Write an equation for each inverse variation.
x = 9 and y = 6
y = 2/3x
y = x/54
y = 3/2x
y = 54/x
3) Suppose y varies inversely with x. Write an equation for each inverse variation.
x = 7 and y = 13
y = 7/13x
y = 13/7x
y = x/91
y = 91/x
4)The pair of points is on the graph of an inverse variation. Find the missing value.
(100, 25) and (4, y)

You can put this solution on YOUR website! 1) The pair of points is on the graph of an inverse variation. Find the missing value.
(14,8) and (x,7)
------
y = k/x --> xy = k
14*8 = k = 112
x*7 = k = 112
x = 16
==========
Don't put a space after the comma.
======================
2)Suppose y varies inversely with x. Write an equation for each inverse variation.
x = 9 and y = 6
y = k/x --> xy = y --> k = 54
y = 54/x
===============
3) Suppose y varies inversely with x. Write an equation for each inverse variation.
x = 7 and y = 13
Same as #2

4)The pair of points is on the graph of an inverse variation. Find the missing value.
(100, 25) and (4, y)
Same as #1
