Question

Suppose the relationship between X and Y is proportional when X is 5, why is 75 identify the constant of proportionality of x to y suppose the relationship between X and Y is proportional. When X is 5, why is 75. Identify the constant of proportionality of x to y

Answer 1

Answer:

The Constant of Proportionality k is 15.

Step-by-step explanation:

Given:

y varies directly with x .

y = 75 when x = 5

To Find:

Constant of proportionality = k =?

Solution:

y varies directly with x .

i.e. y is directly proportional to x

∴ $y = k\times x$

Where

k = constant of proportionality {Remain Same}

So, we will find constant of proportionality k,

∴ When x = 5 and y = 75 we have

∴ $75 = k\times 5\\\\k=\frac{75}{5}$

$\therefore k =15$

Therefore the Constant of Proportionality k is 15.
