HACTEHA [7]

Answer:

$x = 5$

$y = - 5$

Step-by-step explanation:

Look at the second equation.

Add 6y to both sides:

$- 6x = 6y$

Hence,

$y = - x$

Substitute this into first equation:

$- 4x - x = - 25$

$- 5x = - 25$

$x = 5$

Since y = -x,

$y = - 5$

A new truck that sells for 29,000 depreciates 12% each year. What is the decay factor b?

Katena32 [7]

$\bf y=a(b)^t\qquad or\qquad A=I(1-r)^t\qquad \textit{let's check}\\\\
-------------------------------\\\\
\qquad \textit{Amount for Exponential Decay}\\\\
A=I(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &29000\\
r=rate\to 12\%\to \frac{12}{100}\to &0.12\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
A=29000(1-0.12)^t\implies 
\begin{array}{llll}
A=&29000(0.88)^t\\
&\uparrow \qquad\quad \uparrow \\
&a\qquad\quad b
\end{array}$

Find the future value of $1800 deposited at 8% for 5 years if the account pays simple interest, and the account pays interest co

never [62]

For one year:
0.08(1800) + 1800
But because it is 5 years:
5(0.08(1800)) + 1800
0.4(1800) + 1800
We can make it simpler:
1.4(1800)
Multiply:
2520
YOU NOW HAVE $2520
