pochemuha

Answer:

The answer is (4,2)

Step-by-step explanation:

in the point (-4,5) X=-4 AND Y=5

so if you move 8 units right, the X increases by 8(because the  the x axis is left and right) so X transform into 4= -4+8=4

With Y(the y axis is up and down) whe u go 3 units down un decrease the number so Y transforms into 2== 5-3=2

The new coordiantes are(4,2)

Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did
In-s [12.5K]
\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\to &\$450\\
P=\textit{original amount deposited}\to& \$3000\\
r=rate\to r\%\to \frac{r}{100}\\
t=years\to &3
\end{cases}
\\\\\\
450=3000\cdot r\cdot 3\implies \cfrac{450}{3\cdot 3000}=r\implies \cfrac{1}{20}=r
\\\\\\
r\%\implies \cfrac{1}{20}\cdot 100\implies r=\stackrel{\%}{5}
