no, it means 1 divided by the number inverse of 5 is 1/5 inverse of x = 1/x
If you have already determined whether your particular model is direct or inverse variation, then the two models will follow the following functions: Direct: y=kx ---y is always expressible as a constant multiple of x, meaning it varies directly with x by a factor of k Inverse: y=k/x ---y is always expressible as a constant multiple of the inverse of x (1/x). It varies directly with the inverse of x by a factor of k.
multiplicative inverse of 1 plus i is 1 minus i
The inverse of a matrix is used for many different statistics. While you can add, subtract, or multiply matrices, you cannot divide them. However, if you multiple by the inverse of a matrix, this is equivalent to dividing. For example, if you divide 6 by 3 you get 2; however, you could also multiply 6 by the inverse of 3, 1/3, and get the same answer.
