Jenny Baked 231 cookies she kept 48 for herself and divided the rest equally among three fourth grade classes how many cookies d
AVprozaik [17]
Hi there!

First, we'll subtract 48 from 231 because we need to figure out how many cookies in total were given out to the fourth grade classes. This leaves us with 183 cookies for all classes. Then, we need to divide 183 by 3 to figure out how many cookies each fourth grade class got. Doing this leaves us with 61 cookies per class.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

ANSWER

( {y  - 8)}^{2}  =  - 28(x + 5)

EXPLANATION

The given parabola has directrix x=2.

This implies that, the parabola is opens in the direction of the negative x-axis because it must open in a negative direction to the directrix.

The equation of such parabola is of the form:

( {y  - k)}^{2}  = 4p(x - h)

where (h,k)=(-5,8) is the vertex.

|p|  = | - 2 - 5|  = 7

p =  \pm7

But the parabola opens to the left.

p=-7

The equation now becomes

( {y  - 8)}^{2}  = 4( - 7)(x   -  - 5)

( {y  - 8)}^{2}  =  - 28(x + 5)
