The answers A -2  and there is my work :)

Step-by-step explanation: 5x-17 find h(3)

5(3)-17 plug in 3 in the 5x

15-17 subtract 15 and 17

-2

The answer is 2

Step-by-step explanation:

5x - 17

5(3) - 17 = 15 - 17 = -2

However, there is an absolute value sign over the expression. Abs value makes negatives turn positive. So -2 becomes 2.

The number of combinations for picking a number of items from a given selection is found using this formula: nCr = n!/(n - r)!r! where:
n = size of the selection
r = number of items being picked
In the case of the question, there is a selection of 24 people of which 5 will be chosen to sit in the front row so:
n = 24
r = 5
The number of combinations is 24C5 = 42504
Note: scientific calculators, e.g. Casio ones, have a button for the nCr formula.
