~

\tt y=3x+6

\tt x=3y+6

\tt x-6=3y

\tt y=\cfrac{x-6}{3}

How to use graphing to find the solutions to the system of equations?
gayaneshka [121]
Once ur lines are graphed, the solution is where the lines intersect. So by graphing however many equations u have, the point where they intersect is the solution....unless of course u have parallel lines, then there is no solution. And if ur lines are coincident, the same line on top of each other, then there is infinite solutions.

A Poker club has 10 members. A president and a vice-president are to be selected. In how many ways can this be done if everyone
Nesterboy [21]

Answer:

90 different ways

Step-by-step explanation:

We have a total of 10 members, and we want to find how many groups of 2 members we can have, where the order of each member in the group of 2 is important, so we have a permutation problem.

To solve this problem, we need to calculate a permutation of 10 choose 2.

The formula for a permutation of n choose p is:

P(n, p) = n! / (n - p)!

So we have:

P(10, 2) = 10! / (10 - 2)!

P(10, 2) = 10! / 8!

P(10, 2) = 10*9 = 90

So there are 90 different ways of choosing a president and a vice-president.
