Step-by-step explanation:

Using Point - Slope formula :

$(y - y_1) = \frac{(y_2 - y_1)}{(x_2 - x_1)} (x - x_1)$

$(y - 5) = \frac{2}{4} (x - 3)$

2y - 10 = x - 3

$y = \frac{1}{2} x + \frac{7}{2}$

m = 1 / 2

b = 7 / 2

2x + y = 8
x - y = 10
--------------add
3x = 18
x = 6

x - y = 10
6 - y = 10
-y = 10 - 6
-y = 4
y = -4

solution is : (6,-4)

If an investment of $3000 grows to $4432.37 in eight years with interest compounded annually , what is the interest rate?

melamori03 [73]

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\to &\$4432.37\\
P=\textit{original amount deposited}\to &\$3000\\
r=rate\to r\%\to \frac{r}{100}\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{annually, thus once}
\end{array}\to &1\\
t=years\to &8
\end{cases}$

$\bf 4432.37=3000\left(1+\frac{r}{1}\right)^{1\cdot 8}\implies \cfrac{4432.37}{3000}=(1+r)^8
\\\\\\
\sqrt[8]{\cfrac{4432.37}{3000}}=1+r\implies \sqrt[8]{\cfrac{4432.37}{3000}}-1=r
\\\\\\
0.0500001086\approx r\qquad\qquad\cfrac{r\%}{100}\approx 0.0500001086
\\\\\\
r\%\approx 100\cdot 0.0500001086\implies r=\stackrel{\%}{5}$
