indirect variation equation y = x = y x is the blank of variation​

Sagot :

Answer:

Constant of variation

Step-by-step explanation:

Indirect variation equation:

y = k/x  

Where:

  • y varies indirectly with x
  • k  is the constant of variation
  • Indirect variation means as one variable (letter) increases, the other variable (letter) decreases.  They don't increase or decrease their values simultaneously.

Rewrite the equation in terms of its constant:

y = kx

k = xy

Therefore, xy is the constant of indirect variation.

Example:

y = 12  and  x = 2;  Find k, the constant of indirect variation.

Find the constant of variation:

12 = k/2

k = (2)(12)   ⇒   k = (x)(y)

k = 24  

or

(x)(y) = 24
