Question

The pair of points is on the graph of an inverse variation. Find the missing value. (2.4, 3) and (5, y) 1.44 6.25 0.69 1

Answer 1

In verse variation would be 3  = k / 2.4   so k  = 7.2

So we have  y = 7.2 / 5  = 1.44

Answer is 1.44.

Answer 2

Answer:

Hence, the value of y is:

1.44

Step-by-step explanation:

It is given that:

The pair of points is on the graph of an inverse variation.

(2.4, 3) and (5, y)

We have to find the missing value y in the point.

As we know that in the inverse variation the value of y is the inverse value of x by some k.

i.e. in first point (2.4,3) let 'k' be a number such that:

$3=\dfrac{k}{2.4}\\\\k=7.2$

Hence, the inverse is k=7.2

Now in the second point (5,y) we find the value of y as:

$y=\dfrac{7.2}{5}\\\\y=1.44$

Hence, the value of y is:

1.44
