Answer:

6P6 = 720

Step-by-step explanation:

The notation nPk is shorthand for ...

n!/(n-k)!

So your expression

6P6 = 6!/(6-6)! = 6!/0! = 720/1 = 720

_____

The ! is pronounced "factorial." The factorial of a positive integer is the product of that integer and every smaller positive integer. 0! is defined as 1.

6! = 6·5·4·3·2·1 = 720

Answer: $-\frac{8}{77}$

Step-by-step explanation:

$\frac{\frac{4}{7} }{-\frac{11}{2} }$

Multiply by the reciprocal in order to get rid of the fraction in the denominator.

$\frac{\frac{4}{7} }{-\frac{11}{2} }*-\frac{2}{11}$

$\frac{4}{7}*-\frac{2}{11}$

SOLVING ABSOLUTE VALUE EQUATION

Ratling [72]

Answer:

1. x=27

2. x=11 or x=-7

3. x=4

4. x=1 or $x=\frac{1}{3}$

5. x=12

6. x=11 or x=-1

7. x=8

8. x=3 or x=1

9. $x=\frac{13}{2}$ or x=-4

10.x=7 or x=1

Step-by-step explanation:

For the first 8, the absolute value portion is just substituted in for x, so we can skip some of the repeated work that would occur in these. For the absolute value problems, there are two solutions each. When you remove an absolute value, you have to add a plus or minus to each side and solve for each.

1. $5x+9=144\\5x=135\\x=27$
