A parabola with an equation, y2 = 4ax has its vertex at the origin and opens to the right.
It's not just the '4' that is important, it's '4a' that matters.
This type of parabola has a directrix at x = -a, and a focus at (a, 0). By writing the equation as it is, the position of the directrix and focus are readily identifiable.
For example, y2 = 2.4x doesn't say a great deal. Re-writing the equation of the parabola as y2 = 4*(0.6)x tells us immediately that the directrix is at x = -0.6 and the focus is at (0.6, 0)
Answer:
x = 17/2
Step-by-step explanation:
x-3 x+8
------ = ------------
2 6
Using cross products
(x-3) *6 = 2 (x+8)
Distribute
6x - 18 = 2x+16
Subtract 2x from each side
6x-2x-18 = 2x-2x+16
4x-18 = 16
Add 18 to each side
4x-18+18 = 16+18
4x = 34
Divide each side by 4
4x/4 = 34/4
x = 17/2
