<u>ANSWER</u>
<u>EXPLANATION</u>
The given given equation is
We need to rewrite this equation in the slope-intercept form:
We add 3x to both sides.
We divide through by 2 to get,
The slope of this line is
Let the slope of the line perpendicular to this line be 'n' .
Then the product of the slopes of two perpendicular lines is always negative 1.
Therefore the slope of the new line is
They could have assembled total 336 different possible crews.
<em><u>Explanation</u></em>
Total number of trained pilots is 9 and geologists is 4.
The crew should be consisted of 2 pilots and 1 geologist. That means, <u>2 pilots are chosen from total 9 and 1 geologist is chosen from total 4</u>.
Number of ways for choosing 2 pilots from 9 and
Number of ways for choosing 1 geologist from 4
So, the total possible number of different crews they could have assembled
