Xy=k, whenever the product of two variables is a constant it is called inverse variation. This is an inverse relationship, intuitively because, as the value of one variable increases, the other decreases and vice versa.
It is easy to spot as xy=k or y=k/x.
Answer:
Two solutions (-4,-7) and (4,7)
Step-by-step explanation:
x = y + 3
x*y = 28
(y+3)*y=28
y^2+3y-28=0
(y+7)(y-4)=0
y=-7, y=4
x=-4, x=7
Answer:
The value of x = 12, makes the statement 
true
Option D is correct option.
Step-by-step explanation:
What value of x makes this statement true?
We need to solve the equation to find value of x
Subtract 2x on both sides
So, the value of x is: x=12
So, The value of x = 12, makes the statement true
Option D is correct option.
