The pair of point is on a graph of an inverse variation. find the missing value. (9, 5) (x, 6) a: 45 b: 9 c: 7 1/2 d: 3 1/3

you have (9,5) & (x,6)

 so 9 = k/5

k = 9*5 =45

 so 2nd set up have x = 45/6

x = 7.5 = 7 1/2

 Answer is C

C.

Step-by-step explanation:

We have been given a pair of points on a graph of an inverse variation. We are asked to find the missing value for our given point.

We know that when y varies inversely with x, then the equation is: , where, k represents constant of variation.

First of all, we will find constant of variation using point as shown below:

Upon substituting in inversely proportion we will get:

To find the value of x, we will substitute in our equation as:

Therefore, the missing value is and option C is the correct choice.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
