Solve your inequality step-by-step.

7(x+4)>0

Simplify both sides of the inequality.

7x+28>0

Subtract 28 from both sides
.
7x+28−28>0−28

7x>−28

Divide both sides by 7.

7x/7 > −28/7

x > −4

Answer:

So, exist 18564 different possibilities.

Step-by-step explanation:

We know that the eighteen passengers get on an airport shuttle at the airport. The shuttle has a route that includes six hotels, and passengers get off the shuttle at their hotel.

We calcuate how many different possibilities exist that eighteen passengers can choose six hotels. We get:

$C_6^{18}=\frac{18!}{6!(18-6)!}=18564$

So, exist 18564 different possibilities.
