Answer:

Step-by-step explanation:

| 2 - 4a | - 2(b - 7)

let a = 3, b = -5

substitute a = 3, b = -5 into the equation:

| 2 - 4a | - 2(b - 7)

= | 2 - 4(3) | - 2(-5 - 7)

= | 2 - 12 | - 2(-12)

= | -10 | + 24

= 10 + 24

= 34

At a swim meet, 8 different swimmers compete in the 800- meter freestyle race. How many different ways are there for these swimm

nirvana33 [79]

Using the arrangements formula, it is found that there are 40,320 ways for these swimmers to finish.

<h3>What is the arrangements formula?</h3>

The number of possible arrangements of n elements is given by the factorial of n, that is:

$A_n = n!$

In this problem, there are n = 8 swimmers, hence they can finish arranged in 8! ways, that is:

$A_8 = 8! = 40320$
