Directrix y = 8
It is a horizontal line so the parabola is vertical.
<span>The focus (2, 4) lies below the directrix,
Therefore parabola opens downwards. </span>
<span>vertex will be halfway between focus and directrix, at (2, 6) </span>
<span>focal length =p
= distance between focus and vertex
= 2 </span>
<span>y = (-1/(4p))(x - 2)² + 6 </span>
<span>y = (-1/8)(x - 2)² + 6
hope this helps</span>

d) it is
e) it isn't
f) it isn't
Answer:
y = mx + b would be your starting equation. You need two coordinates for to find your slope (mx). You multiple your slope (m) with your x-coordinate given (x). Then after multiplying, you subtract that with y to find your b. Thus, the answer. You'll want to ask yoru teacher for more help if you don't get it. :)
Answer:
$1,440
Step-by-step explanation:
Explanation: well, 30% of 4,000 is $1,200 so i think the answer is B if the income is $4,800, then the answer would automatically be $1,440. ❤️
