2x + 8 = 50
Subtract 8 from both sides
2x = 42
Divide both by 2
x = 21
Well, "<span>the set of all points in the plane equidistant from the focus and a line", is referring to the focus point of the parabola and the directrix line.
bearing in mind that, both fellows are at a distance "p" from the vertex, that puts the vertex right in the middle of them.
notice, the focus point is below the directrix, meaning, is a vertical parabola, and is also opening downwards, like in the picture below.
from -5 to 5 over the y-axis, there are 10 units, so the "p" distance is 5, so that puts the vertex right at the origin.
since the parabola is opening downwards, "p" is negative, thus -5.

Answer:
10 shirts
Step-by-step explanation:
We can use a ratio to solve
50 dollars 125 dollars
-------------------- = -------------------
4 shirts x shirts
Using cross products
50 *x = 4 * 125
50x = 500
Divide each side by 50
50x/50 = 500/50
x = 10
