Answer:
since both numbers have the same sign the rule of "same sign keep the sign" applies and since they are both negative instead of subtracting you add if they were the inverse of each other you would have to subtract but clearly that isn't needed in this situation.
hope that helps a little!!

Step-by-step explanation:
The symbol ₁₂P₉ represents the permutations of 9 quantities out of 12.
By definition,
![_{12}P_{9} = \frac{12!}{(12-9)!} = \frac{12!}{3!}](https://tex.z-dn.net/?f=_%7B12%7DP_%7B9%7D%20%3D%20%20%5Cfrac%7B12%21%7D%7B%2812-9%29%21%7D%20%3D%20%5Cfrac%7B12%21%7D%7B3%21%7D%20)
From the calculator,
12! = 479,001,600
3! = 6
Therefore
₁₂P₉ = 479001600/6 = 79,833,600
Answer: 79,833,600
Yes it is balanced because all aspects are there
Given:
Unit base price: $435
Credit Card interest rate, i = 9.4% compounded monthly; i = 0.00783/month comp monthly
n = 1.5 years = 18 months
sales tax = 8.51%
First, determine the actual price of the unit by adding the sales tax to the base price of the unit:
$435 * (1 + 0.0851)
Actual price = $472.0185
So, the total amount paid by Brian should be higher than the actual price since he used his credit card. Use the formula from economics:
F = P (1+i)^n
F = $507.96
Therefore, the total amount paid by Brian is $507.96.
