If p and q vary inversely, and p=10 when q=-4 , the value of q will be 20 when p=-2.
A mathematical constant is a significant integer that has a steady value and is specified by a precise definition.
relationship between two variables in mathematics that may be represented by an equation where the product of their products equals a constant
Inverse variation is y = k. 1/x
given p = -4
q = 10
So, 10 = k. 1/-4
So, the value of k = -40
We can conclude that the value of constant variation is -40
Value of q, when p = -2
⇒ q = -40 / -2
⇒ q = 20
