Answer:

Step-by-step explanation:

-3x+3y=-18 ➡3y=3x-18 ➡y=x-6

5x-2y=9➡-2y=-5x+9➡y=2.5x-4.5

2.5x-4.5=x-6

1.5x=-1.5

x=-1

y=-1-6

Suppose you invest $400 at an annual interest rate of 7.6% compounded continuously. How much will you have in the account after

likoan [24]

$\bf ~~~~~~ \textit{Compounding Continuosly Interest Earned Amount}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$400\\
r=rate\to 7.6\%\to \frac{7.6}{100}\to &0.076\\
t=years\to &1.5
\end{cases}
\\\\\\
A=400e^{0.076\cdot 1.5}\implies A=400e^{0.114}$

How do you solve this question /

Alinara [238K]

Answer:

5/18

Step-by-step explanation:

Parentheses next to each other mean to multiply. So, this problem means you need to multiply -4/9 and -5/8. To multiply fractions, you just have to multiply across. To make it easier to understand what I mean...

-4 x -5 = 20 (when you multiply two negatives, it makes a positive)

9 x 8 = 72

20/72 simplifies to 5/18.

Hope this helps!! Have a wonderful day C:

What is the radius of a sphere if its surface area is 2,122.64 square inches? (Use 3.14 for .)

Lady_Fox [76]

$\bf \textit{surface area of a sphere}\\\\
SA=4\pi r^2~~
\begin{cases}
r=radius\\
------\\
SA=2122.64
\end{cases}\implies 2122.64=4\pi r^2
\\\\\\
\cfrac{2122.64}{4\pi }=r^2\implies \cfrac{530.66}{\pi }=r^2\implies \sqrt{\cfrac{530.66}{\pi }}=r$
