Answer:

y= -6

Step-by-step explanation:

<u>-4y - 20 + 19 = -y + 17</u>        *add y on the right to get rid of -y

+y                    +y                then add it to -4y

<u>-3y - 20 + 19 = 17</u>               *add 20 to the left to get rid of -20  

     +20           +20              then add it to 17

<u>-3y + 19 = 37</u>                      *subtract 19 from the left to get rid of 19

       -19    -19                      then subtrcat 19 from 37 as well

<u>-3y</u> = <u>18</u>                             *now we want to divide both sides by -3 to

-3      -3                               get y by it's self

y = -6                                *no we're left with y = -6 :D

- im sorry if this doesn't make sense x(

Answer:

The difference is 5.

Step-by-step explanation:

The difference in math means subtraction, therefore, we need to find how many pints of strawberries she packs separately in the morning and in the afternoon:

3 pints ever 4 minutes.

60 minutes in an hour.

60 / 4 = 15 pints per hour.

2 pints of strawberries every 3 minutes in the afternoon.

60 / 3 = 20 pints per hour.

The difference between afternoon and morning **per** hour:

20 per hour - 15 per hour = 5

Difference is 5.

PLEASE HELP!

Answer:

  f(x) = (x +6)^3 +4

Step-by-step explanation:

f(x -h) +k is the function f(x) translated by (h, k). You want to translate the function by (-6, 4), so it will be ...

  f(x +6) +4 = (x+6)^3 +4

The translated function is ...

  f(x) = (x +6)^3 +4

  f(x) = x^3 +18x^2 +108x +220 . . . . . . with parentheses eliminated

_____

The graph shows the two versions of the translated function. One is dashed so you can see the other has the same graph.
