I actually have 5 questions on the same thing, just different setups. But how would I go about solving them? .-.
Ivanshal [37]
<span>1)  2p = -2.
<span>     4p [ y - k ] = [ x - h) ]² --- > - 4 [ y + 5 ] = [ x + 5 ]²
2) </span></span><span>4p * (y - k) = (x - h)^2 </span>

<span>(h , k) is the vertex </span>

<span>The vertex is halfway between the focus and the directrix (when they're at their closest) </span>
<span>p is that distance </span>

<span>2 - 1 = 1 </span>
<span>4p = 1 </span>
<span>p = 1/4 </span>

<span>(1/4) * (y - k) = (x - h)^2 </span>
<span>y - k = 4 * (x - h)^2 </span>

<span>The vertex is at (6 , 3/2), since that's midway between (6 , 1) and (6 , 2) </span>

<span>y - 3/2 = 4 * (x - 6)^2 </span>
<span>y = (3/2) + 4 * (x - 6)^2 
</span><span>
4) </span><span>f(x) = (-1/16)*(x²)

5) </span><span>f(x) = −1/4 x2 − x + 5</span><span>

URGET!!! IM TAKING A TEST. DUE TODAY
Novay_Z [31]

Answer:

15x \geq 345

x = number of hours she works

Step-by-step explanation:

First: find the inequality symbol

If she wants to earn at least 345, she wants to make 345 or more

that means you use the greater than or equal symbol (\geq)

Next, if she makes 15 dollars an hour, x has to be the number of hours she works. The left side of the inequality would be $15* number of hours, or 15x

Thus, your inequality would be 15x \geq 345

Pls help i know x= 8
patriot [66]

Answer:

if x=8 then m<2=32, and m<3=36 and d=112 because the other side of angle 3 and 2 is the same so you know a triangle is 180 so 180-68=112.
