Question

if x varies directly as y the equation of variation is expressed as X multiple by Y = K . true or false​

Answer 1

Answer:

TRUE

Step-by-step explanation:

DIRECT VARIATION. y=Kx. K≠0

asume y varies directly as x

* If y=6 when x =12, find x when y =9

we can do this problem by 2 ways.

*Write the equation y= Kx and substitute in the first pair to find K

where x and y are the two quantities and K is

the constant of variation.

y

another way of writing this - K _

x

hope it will help you ☺️

Answer 2

Given,

x varies directly as y.

Solution,

Therefore, the variation of x multiplied by y

$\[\begin{array}{l} \Rightarrow x = ky\\ \Rightarrow \frac{x}{y} = k\end{array}\]$

Hence, the given statement is FALSE.
