Solve (x + 2 < 5) ∩ (x - 7 > -6).

mihalych1998 [28]

Answer:

Step-by-step explanation:

x + 2 < 5 <em>subtract 2 from both sides</em>

x + 2 - 2 < 5 - 2

x < 3

x - 7 > -6 <em>add 7 to both sides</em>

x > 1

From x < 3 and x > 1 we have 1 < x < 3

The amount of money in a savings account after t years is represented by the function f(t)=500(1.015)t.

Sauron [17]

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\\
r=rate\to r\%\to \frac{r}{100}\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
f(t)=\stackrel{\stackrel{I}{\downarrow }}{500}(1.015)^t$
