Would -x - 3y = -1 convert into y = -1/3 x - 1/3​
vfiekz [6]

Answer:

Yes, -x - 3y = -1 is the same as y = -1/3x - 1/3

Step-by-step explanation:

-x - 3y = -1

Add x to both sides which gives you

-3y = x-1

Divide both sides by -3 which gives you

y = -1/3x-1/3

Reminder whatever you do to one side you have to do to the other side!

Hope this helps!

Jacob and Zachary go to the movie theater and purchase refreshments for their friends. Jacob
son4ous [18]
Ok lets say
popcorn = x and
drinks = y

Jacob:      2x + 3y = 18.25
Zachary:   4x + 2y = 27.50

ok now you have to use these 2 equations to get the answer

4x + 2y = 27.50  --->   2y = 27.50 - 4x   --->  y = 13.75 - 2x

2x + 3y = 18.25
2x + 3(13.75-2x) = 18.25
2x + 41.25 - 6x = 18.25
-4x + 41.25 = 18.25
-4x = -23
x = 5.75             <u><em>One bag of popcorn is $5.75</em></u><em />


4x + 2y = 27.50
4(5.75) + 2y = 27.50
23 + 2y = 27.50
2y = 4.50
y = 2.25             <u><em>One drink is $2.25</em></u><em />

What is the compounded interest if $410 is invested for 10 years at 8% compounded continuously
tatiyna
\bf \textit{Continuous Compounding Amount}\\\\&#10;A=Pe^{rt}\qquad \begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{original amount deposited}\to& \$410\\&#10;r=rate\to 8\%\to \frac{8}{100}\to &0.08\\&#10;t=years\to &10&#10;\end{cases}

so, that gives you  the compounded amount, after 10 years, if you want to know how much interest was earned? well, just subtract the Principal from the Amount, or A - P  <--- that's how much interest was earned
