<span>Find the focus and directrix of the parabola with the given equation. Then graph the parabola.
y^=-12x
**
y^2=-12x
This is an equation of a parabola with a horizontal axis of symmetry.
Its standard form: (y-k)^2=4p(x-h), with (h,k) being the (x,y) coordinates of the vertex.
For given equation:
Vertex(0,0)
4p=12
p=3
Focus:(-3,0)
Directrix: x=3

y=±(-12x)^.5</span>
I see 4 pairs of vertical angles and they are:
7/9
8/10
11/13
12/14
<span>4(z-5)+2=4z-18
4z - 20 + 2 = 4z - 18
4z - 18 = 4z - 18
0 = 0

It would be: 296*42 / 100 = 12432/100 = 124.32
so, your answer is 124.32
