Question

The pair of points is on the graph of an inverse variation. Find the missing value.
(5,4) and (x,7)

A: 2 6/7
B: 20
C: 5
D:5 3/5

Answer 1

Answer:

pls mark as brainliest bevause i wasted time in this

Step-by-step explanation:

The inverse variation is given by:  

Now convert this into an equation we must multiply the constant variation k we get,



To find the value of k;

use the coordinates (5,4) , where x =5 and y =4

then,

 or



On Simplify, we get:

k = 20

the equation become:  

When y =7 we have;

  

(x ,7) = 

therefore, the missing value x is,
