Answer:
So for the first one the first ting u have to do is FLIP the equation so---> X-12=y
Then you have to add 12 to BOTH sides----> x-12+12=y+12
<u><em>So your answer for X ----> x=y+12</em></u>
<u><em>For Y on the first equation it is--->y=x-12</em></u> (Just flipped and the sign changed)
For the second equation we are gonna solve for Y first.
The first thing u want to do is divide both sides by -3 so it will look like this
-3y/-3 = 2x/+36/-3
<u><em>So Y will equal-----> -2/3x- 12</em></u>
Now we are going to do the X part
So fist FLIP the equation----> 2x+36= -3y
The add -36 to both sides-----> 2x+36+-36=-3y+-36
Last step you have to divide both sides by 2
So that would be----> 2x/2= -3y-3
<u><em>Your final result will be----> x=-3/2y-18</em></u>
I hope this helped you out (:::::::
Answer:
125.0272
Step-by-step explanation:
7 (1.14)^22
Each hour it grows 14%. This means after 1 hour, it has grown 7*1.14. After two hours 7*1.14 (1.14) or 7*(1.14)^2, etc so after 22 hours use equation above to solve.
