<h3>
Answer: 680 different combinations</h3>
=======================================================
Explanation:
If order mattered, then we'd have 17*16*15 = 4080 different permutations. Notice how I started with 17 and counted down 1 at a a time until I had 3 slots to fill. We count down by 1 because each time we pick someone, we can't pick them again.
So we have 4080 different ways to pick 3 people if order mattered. But again order doesn't matter. All that counts is the group itself rather than the individual or how they rank. There are 3*2*1 = 6 ways to order any group of three people, which means there are 4080/6 = 680 different combinations possible.
An alternative is to use the nCr formula with n = 17 and r = 3. That formula is

Answer:
20 18. on the answer is 18 and 20 give me the brainlyest
Less then or equal to, and your sign is pointing the wrong way I believe.
Answer:
(x,y) + (x-4, y)
Step-by-step explanation:
horizontally means it would be on the x axis traveling to the left would be your subtracting there fore the only answer which comes with a x-4 is (x,y) + (x-4, y)
