1/12 because if you multiply both the fractions you get that.
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:
Subtract 19 both sides.
Divide 7 on both sides to isolate x.
-->
Transform form improper to proper form.
The second option!
4(3x + 5y + 1)
4 x 3x = 12x
4 x 5y = 20y
4 x 1 = 4
Which equals 12x + 20y + 4!
I hope this helped! Have a nice day! ~(^v^)~
