We know that
Any point <span>(x,y)</span> on the parabola is equidistant from the focus and the directrix
Therefore,
focus (0,4) and directrix of y=2
<span>√[<span>(x−0)</span></span>²+(y−4)²]=y−(2)
<span>√[x</span>²+(y-4)²]=y-2
x²+(y-4)²=(y-2)²
x²+y²-8y+16=y²-4y+4
x²=4y-12-----> 4y=x²+12----->y= (x²/4)+3
the answer is
y= (x²/4)+3

Answer:
A: x<0
Step-by-step explanation:
Hopefully this helps!
<em>We let...</em>
<em>x as the number of months he spent in Portugal</em>
<em>y as the number of months he spend in Brazil</em>
<em>From the problem, we can generate the following equations</em>
<em>x + y = 14</em>
<em>130x + 150y = 1920</em>
<em>Solving the equation gives us</em>
<em>x = 9 months in Portugal</em>
<em>y = 5 months in Brazil</em>
