A permutation, "also called an arrangement number, is a rearrangement of the elements of an ordered list S into a one-to-one correspondence with S itself. The number of permutations on a set of n elements is given by n! factorial".

The formula for permutation is given by:

Solution to the problem

We are interested in find 45P2, if we use the last formula we got this:

Now we can use the following property for the factorial operation:

So using this two times we can rewrite the expression 45! on this way:

And replacing this we got:

We can cancel the 43! of the numerator with the 43! of the denominator and we got:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

x-3y=4
