Considering the equation of the parabola, the directrix is: x = 1.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of an horizontal parabola, of vertex (h,k), is given by:
(y - k)² = 4p(x - h).
The directrix is at x = h - p.
For this problem, the equation is:
(y + 3)² = 8(x - 3).
The relevant coefficients for this problem are:
4p = 8 -> p = 2, h = 3.
Hence the directrix is:
x = h - p = 3 - 2 = 1.

Answer:

Step-by-step explanation:
You can add the exponents of x^3*x^4 instead of writing it all out. Do you would just have to add 3+4 since the variable (x) is the same. And you would get x^7
Hello keirabug, I am here to answer your question:
Since 10^3 is the same as 10*10*10, or 1000, and each CD is worth 12$, then 1000 * 12$ is equal to 12000$
But for the CD players, it's 10^2 or 10*10, which gives us 100, and each CD player is worth 35$, so 100 * 35$ is equal to 3500$
And then we do an addition to add the prices like this: 12000$ + 3500$ = 15500$
So the answer is 15500$
Hope this helped you!
Answer is A.
step 1 , 16 was not multiplied by 9
should be
54x - 9y = 144
