Y=k/x where k is the constant of proportionality is an example of indirect or inverse variation. They are the same thing.

What does inverse variation mean?
Two variables X and Y are in inverse variation if X*Y = c for some non-zero constant c.
What does variation mean in math terms?
There are different types of variation in math - direct variation, inverse variation, and joint variation for a start. Direct variation is just simply that x and y vary directly. What this means is that they do the same thing - as x increases so does y, or as x decreases so does the value of y. In general the formula for direct variation is y=kx where k is the constant of variation. (For example we could have a direct variation equation such as y=2x. The constant of variation is 2, which just means that as x increases, y doubles that amount and thus also increases) Inverse variation is when x and y do the opposite of each other. So as x increases, y decreases or as x decreases the value of y increases. One fun example of where this happens in real life is with Ramen Noodles - the less money people make the more Ramen Noodles they buy. We would say that people's income and the amount of Ramen Noodles they buy vary inversely. In general the formula for inverse variation is y = k/x where again k is the constant of variation. Joint variation is when you have three variables that are related. The general formula for joint variation is y=kxz where z is just a third variable and k is still the constant of variation.
What is the inverse of -7 plus 5?
It depends on whether you mean additive inverse or multiplicative inverse.
What does inverse mean in arithmetic?
"opposite" operation. The inverse of subtraction is addition; the inverse operation of multiplication is division.
Does inverse mean opposite?
no, it means 1 divided by the number inverse of 5 is 1/5 inverse of x = 1/x

In maths what does inverse mean?
The inverse operation is just the opposite operation, for example addition is the inverse of subtraction, and vice verso

"opposite" operation. The inverse of subtraction is addition; the inverse operation of multiplication is division.
What does indirect mean in a sentence?
Indirect means not direct. We got there by indirect means. The author used indirect characterization.
Does inverse mean opposite?
no, it means 1 divided by the number inverse of 5 is 1/5 inverse of x = 1/x
What does inverse property in multiplication mean?
Some one please tell me what inverse property is!!
What does indirect mean?
Indirect means diverging from a straight line/path, not going straight to the point,the opposite of direct. It is used to mean a roundabout or covert method of action, in terms such as indirect taxes, indirect characterization, or indirect criticism.
Does multiplicative inverse mean opposite?
no
What does the word inverse mean in math terms?
Mathematically, an inverse is an opposite, it is something that reverses what its inverse does, for example, addition and subtraction are inverse functions, as are multiplication and division. The inverse of a fraction is obtained by exchanging numerator and denominator; the inverse of a half is two.
Determine Coefficient of variation from the mean and standard deviation?
Coeff of Variation = Mean/SD
