b) -4
- 8x +4 =36
First, we subtract 4 from 36 to get 32
36-4=32
-8x=32
Since a negative times a negative equals a positive, then the answer has to be negative because 36 is positive.
32 divided by 8 = 4
B) -4
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.

Answer should be 3 I’m pretty sure
Do you mean ^2? cause if so... B don't really need crit points to solve, the parabola has a positive slope before x =2
