Answer:

2 =x

Step-by-step explanation:

f(x) = 9 - 4x

Let f(x) = 1

1 = 9 -4x

Subtract 9 from each side

1-9 = 9-4x-9

-8 = -4x

Divide by -4

-8/-4 = -4x/-4

2 =x

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:

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

2*8*5=2*5*8 identify the property that is shown

ira [324]

The property shown is commutative multiplication. This property says that the product of two factors is not affected by the order in which they're multiplied. In this case, the product remains the same i.e., 2*8*5 = 80 while 2*5*8 also equals 80.
