The equation of the directrix of the parabola given is x = 6, Option D is the correct answer.
<h3>What is Directrix of a Parabola ?</h3>
A parabola is a U shaped curve whose all point are at same distnace from a point called as focus and a line called as Directrix .
The equation of the parabola given is
y² = -24x
When the standard equation of parabola is
(y - k)² = 4p (x - h),
where the focus is (h + p, k) and the directrix is x = h - p.
here h = 0
p = -24/4 = -6
x = 0 - (-6)
x = 6
Therefore Option D is the correct answer.

Answer:
-2 7/10
Step-by-step explanation:
A − 3b = 16
a = b − 2
b - 2 - 3b = 16
2b = - 18
b = - 9
a = - 9 - 2
a = - 11
(-11,-9)
There aren't any functions listed to choose from, but it should look something like the following:
E= total earnings that day
h= # hours worked that day
n= # people served that day
E= 7h + 5n
substitute 6 hours in for h
E= 7(6) + 5n
E= 42 + 5n OR E= 5n + 42
Hope this helps! :)
