Answer:
C) 
The slope of the perpendicular line
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the slope of the given line is
The slope of the perpendicular line
= 
The slope of the perpendicular line
= 
<u><em>Final answer</em></u>
The slope of the perpendicular line
9 more than y is an expression so it would be 9+y
This is how you do it.
y = a(x - 3)(x - 8)
<span>-2 = a(-1 - 3)(-1 - 8) </span>
<span>-2 = 36a </span>
<span>- 1 / 18 = a </span>
<span>y = ( - 1 / 18)(x^2 - 11x + 24) </span>
<span>y = (- 1 / 18)x^2 + (11 / 18)x - (3 / 2)
</span>
If this doesn't explain it enough, please, ask questions.
The final grade of fran can be calculated
by multiplying the corresponding percentage of his average homework, quizzes
and tests, then sum it up and it is now the final grade of fran.
Final grade = (0.10 x 92) + ( 0.20 x 68) +
(0.70 x 81)
<span>Final grade = 79.5 </span>
