Using the combination formula, it is found that he has 232 choices.
The order in which the sights are seen is not important, hence the <em>combination formula </em>is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
In this problem, the choices are 8, 9, 10 or 11 sights from a set of 11, hence:
![T = C_{11,8} + C_{11,9} + C_{11,10} + C_{11,11} = \frac{11!}{3!8!} + \frac{11!}{2!9!} + \frac{11!}{10!1!} + \frac{11!}{0!11!} = 232](https://tex.z-dn.net/?f=T%20%3D%20C_%7B11%2C8%7D%20%2B%20C_%7B11%2C9%7D%20%2B%20C_%7B11%2C10%7D%20%2B%20C_%7B11%2C11%7D%20%3D%20%5Cfrac%7B11%21%7D%7B3%218%21%7D%20%2B%20%5Cfrac%7B11%21%7D%7B2%219%21%7D%20%2B%20%5Cfrac%7B11%21%7D%7B10%211%21%7D%20%2B%20%5Cfrac%7B11%21%7D%7B0%2111%21%7D%20%3D%20232)

Answer:
The answer is (x -5, y -3)
Step-by-step explanation:
Answer:
Step-by-step explanation:
3y – 6x = 3 -----------------------------------(I)
y = 2x + 1 ----------------------------------(II)
Substitute y = 2x + 1 in equation (I)
3*(2x+ 1) - 6x = 3
3*2x + 3*1 -6x = 3
6x + 3 - 6x = 3
3 = 3
So, no solutions
