Gnoma [55]

Answer:

10 pairs

It is a combination

Explanation:

This is a combination because the order does not matter: the Beagle - Collie couple is the same as the Collie - Beagle couple, so it is only counted once.

The formula for combinations is:

$C(m,n)=\dfrac{m!}{n!\cdot (m-n)!}$

For five diffferent dogs to be put in pairs, the number of different pairs is:

$C(5,2)=\dfrac{5!}{2!\cdot (5-2)!}=\dfrac{5\times 4}{2}=10$

What is the solution to the system of equations?

elixir [45]

Answer:

No solution

Step-by-step explanation:

$-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9\\\\$

Lets consider the equation 2.

Here we multiply the LHS and RHS with (-1).

$-3x-4y-3z=-7\\-(2x-6y+2z)=-3\\5x-2y+5z=9\\\\$

Hence,

$-3x-4y-3z=-7\\-2x+6y-2z=-3\\5x-2y+5z=9\\\\$

When we add the equations we get,

$0x+0y+0z=-10+9\\Hence,\\0=-1$

As 0 doesn't equal to -1, answer is d) No solution

To find the answer to a problem like this, we need to look for patterns in the number!

It looks likes x = 2y

Or in other words, (y is being multiplied by 2 to find x!)

**Now that we've discovered this pattern, we can confidently say that ...
