Answer:
3x^3-2x^2-19x-6
Step-by-step explanation:
= 3x^2x+3x^2(-3)+7xx+7x(-3)+2x+2(-3)
= 3x^3 - 2x^2 - 19x - 6
Key - (^) means exponent
First, set up an equation to model the problem. I will use the simple interest formula: I = (P)(r)(t); where P = principle amount, r = interest rate, and t = time.
First, substitute the known values into the formula:
P = $250
r = 0.3% = 0.003
t = 2
I = (250)(0.003)(2)
Now, all we have to do is simplify to find the amount of interest that will be added to Sydney's account after two years.
I = (0.75)(2)
I = 1.5
After two years, $1.50 will be added to Sydney's account. To find the total amount of money she will have after that time, just add the interest to her initial deposit:
250 + 1.5 = 251.50
So, your final answer is...
After two years, Sydney will have $251.50 in her account.
Hope this helps!

Answer:
x = -15
Step-by-step explanation:
7 + (2/5)x = 1
First, divide two by five to get 0.4, then substitute in the choices given (remembering that you must also add seven afterward).
0.4*-15 = -6 -6 + 7 = 1 = 1
And there you have it!
*It is important to double check your answer by testing other numbers as well.
