Which of the coordinates listed below could represent a point found on the line 3x?

Kamila [148]

Well.. You seem to have forgotten to add the coordinates...

Anyway, the line is represented by the function f(x) = 3x .

Any point which follows the form (x,3x) will be on the line

for example (-3,-9) ; (-2,-6) ; (-1,-3) ; (0,0) ; (0.333333,1) ; (1, 3) ; (2,6) ; (3,9) ; and so on....

How many ways can 8 books be arranged on a shelf? Show all of your work for full credit.

Aneli [31]

Answer:

40,320.

Step-by-step explanation:

We are asked to find the number of ways in which 8 books could be arranged on a shelf.

The 1st could be arranged in 8 ways. Since one place is filled, so 2nd book could be arranged in 7 ways.

Similarly, the 3rd book could be arranged in 6 ways as first two places are already taken. This process will go on.

So the 8 books can be arranged in $8\times 7 \times 6\times5\times4\times3\times2\times1=8!$

$8!=40,320$

Therefore, 8 books could be arranged in 40,320 ways.
