Answer: y=-1/3+2/3

Step-by-step explanation:

1. 6x-2y=7 subtract 6x from both sides.

2. -2y=-6x+7 divide both sides by -2 to isolate y

3. y=3x+7 that’s the y=Mx+b format, now we must find the negative inverse of the slope (m) which is -1/3.

4. Plug in variables.

-5=-1/3(4)+b

5. Solve:

-5=-4/3+b

add 4/3 to both sides to get -3 2/3=b

6. Make y=mx+b equation.

y=-1/3x+2/3

11000 is compounded semiannually at a rate of 12% for 21 years. Find the total amount in the compound interest account

marishachu [46]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\dotfill &\$11000\\
r=rate\to 12\%\to \frac{12}{100}\dotfill &0.12\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{semiannually, thus twice}
\end{array}\dotfill &2\\
t=years\dotfill &21
\end{cases}$

$\bf A=11000\left(1+\frac{0.12}{2}\right)^{2\cdot 21}\implies A=11000(1.06)^{42}\implies A\approx 127127.359416$
