Answer:
Step-by-step explanation:
We have that the focus is at (p,0) and that the directrix is x=-p. Take the point (-p,0) of the directrix. We know that the vertex of the parabola is at the middle point ot the line segment that joins the points (p,0) and (-p,0). To get the middle piont, we take the average coordinate by coordinate. That is, the middle point is 
. The general formula of a parabola of vertex (h,k) that opens to the right or to the left is given by
Where |p| is the distance from the focus to the vertex. If the parabola opens to the right, then p>0 and p<0 otherwise. In our case, h =0=k, so we get that

Answer:
The amount of money in his paycheck was $ 225.
Step-by-step explanation:
Given that Li put $ 75 into his savings account, and said money was 1/3 of his paycheck, to determine which equation could be used to find the amount of money, p, in dollars, on his paycheck, the following reasoning must be performed mathematical:
75 / (1/3) = P
75 / 0.333 = P
225 = P
Thus, the amount of money in his paycheck was $ 225.
