Answer:

On this case n =6 and x =6 we got:

Step-by-step explanation:
The utility for the combination formula is in order to find the number of ways to order a set of elements
For this case we want to find the following expression:

And the general formula for combination is given by:

On this case n =6 and x =6 we got:

Answer:

Step-by-step explanation:
Recall that
. Using this, we can simplify and combine the two terms:
. Therefore, the terms may be combined.
3 subtracted from twice a number=2x-3
8 less than the number=x-8
2x-3=x-8
x=-5
Answer:
<em>y = 3x + 1</em>
Step-by-step explanation:
y = mx + b
The slope, or <em>m</em>, is 3.
The y-intercept, or <em>y</em>, is 1.
Plug them into the equation.
y = mx + b
<em>y = 3x + 1</em>
It is 784 cubic inches so you are right
