The parentheses just means multiplication.
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 .

= $ 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 .

= $ 310 .
THE TOTAL INTEREST EARNED = $ 75 + $ 310
= $ 385

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
(x,y)
(4,6)
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 :)
Id say the correct answer is D, work looks good
