Intercept form is: y = a(x - p)(x - q)
It is given that: p = 14, q = -6, x = 14, y = 4
4 = a(14 - 12)(14 - (-6))
4 = a(2)(20)
4 = 40a
Answer: y = (x - 14)(x + 6)
Using the combination formula, it is found that 2,220,075 committees can be formed.
The order in which the people are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
<h3>Combination formula: </h3> is the number of different combinations of x objects from a set of n elements, given by:
In this problem, 8 people are chosen from a set of 12 + 15 = 27, hence:
2,220,075 committees can be formed.
