Check the picture below, notice the distance from the focus to the directrix
bear in mind that, the vertex is a distance "p" from the focus point and a distance "p" from the directrix, that simply means, the vertex is half-way between both of those fellows
in this case, the focus point is above the directrix, that means, the parabola is vertical and opens upwards, "p" is a positive number for the focus/point form
so.. check the graph, you know what h,k are, and p, so, plug them in
<span>Vertical angles are equal</span>
6x - 10 = 5x + 15
6x - 5x = 15 + 10
x = 25

"Let There Be a Gas Phase"
There, a type of material called kimberlite magma causes the solid rock to break its way up from deeper into the mantle of Earth. The magma gathers fragments of rocks as it rises, like floodwaters gathering up silt and gravel. Diamonds are contained in some of these fragments.
