If order mattered, then there would be 6*5*4*3 = 30*12 = 360 different ways to form the committee. However, no single member outranks the other. Each member has equal ranking. So order does not matter.
Since order does not matter, we must consider all of the ways to arrange a single group of 4 people. That is 4! = 4*3*2*1 = 24 ways. We overcount by a factor of 24 when order doesn't matter which is why we divide the previous result (360) by 24 to get 360/24 = 15
Answer: 15
Note: you can use the combination formula n C r = (n!)/(r!*(n-r)!) with n = 6 and r = 4 to get the same answer
Hello!
Note that when seeing an odd number of negatives next to each other, it will remain negative, while having an even number would be positive. For example, -- is +, while --- is -.
Based on this information, we can rewrite the equation below.
2-1/8-7/4
Let's rewrite 7/4 out of 8.
2-1/8-14/8
2-15/8
Let's rewrite 2 as an improper fraction.
16/8-15/8=1/8
Therefore, our answer is 1/8.
Answer:
A is the answer when graphed the asym-ptote is y=0 so the the horizontal asym-ptote is y=0
Step-by-step explanation:

First we work out the brackets


Now we add -2x to both sides of the equation

Hence, the anser is
x > -8
