In which of the tables below x and y are inversely proportional? Find the constant of variation.
sertanlavr [38]

Answer:

In Table (b)

k=30

Step-by-step explanation:

 By definition, Inverse proportion equations have he following  form:

y=\frac{k}{x}

Where "k" is the Constant of proportionality.

Solving for "k":

k=yx

Having the values of "x" and "y" given in each table, you can check if the products of "x" and "y" is equal to a constant value.

Then:

(a) For x=3;y=8:

(8)(3)=24

For x=4;y=6:

(6)(4)=24

For x=5;y=4.8:

(4.8)(5)=24

For x=5.5;y=4:

(4)(5.5)=22

Since the product of the values of "x" and "y" is not constant, they are not inversely proportional.

(b) For x=0.1;y=300:

(300)(0.1)=30

For x=0.5;y=60:

(60)(0.5)=30

For x=75;y=0.4:

(0.4)(75)=30

For x=100;y=0.3:

(100)(0.3)=30

Notice that the Constant of proportionality is:

k=30

Therefore "x" and "y" are inversely proportional.
