Sal Boxer decided to divide a gift of $5000 into two different accounts. He placed $1000 in an account that earns an annual simp
mash [69]

Answer:

THE TOTAL INTEREST EARNED = $ 385

Step-by-step explanation:

Interest earned by sal from first account can be calculated as follows :

Principal value (P)  =  $1000 .

interest rate (R)  =  7.5 % .

Time period (T) =  1  year .

\textbf{S . I} =\frac{\texbf{P * R * T}}{\textbf{100}}

        = \frac{1000 * 7.5 * 1}{100}

         = $ 75 .

SIMILARLY , we can find the intrest earned by rest amount.

Principal value (P) = $5000 - $ 1000 = $ 4000 .

Interest rate (R) = 7.75 % .

Time period (T) = 1 year .

S . I =  \frac{4000 * 7.75 * 1}{100}

      = $ 310 .

THE TOTAL INTEREST EARNED = $ 75 + $ 310

                                                       = $ 385

How do i use systems of equations to eliminate two problems that are: -9x+2y=-24 and -x+2y=8
gulaghasi [49]
Eliinate y's
multiply top eqatyion by -1 and add to 2nd

9x-2y=24
<u>-x+2y=8 +</u>
8x+0y=32

8x=32
divid both sides b y8
x=4

sub back

-x+2y=8
-4+2y=8
add 4 to both sides
2y=12
divide both sides by 2
y=6

:) y = (3 - x)(x + 2)​
valentina_108 [34]

Answer:

-x² + x + 6

Step-by-step explanation:

Hey there!

To solve this, you have to use foil...

( 3 - x ) ( x + 2 )

3 ( x + 2 ) = 3x + 6

-x ( x + 2 ) = -x² - 2x

3x + 6 - 2x - x²

-x² + x + 6

Hope this helps :)
