Dish is not a great deal but it is a great way of getting the right next round to get the rest of the meal to go to a table and brown rice SIKE
You use the first formula. You plug in the values to get A=400(1+(0.05/1))^6. You should get approximately $536.04. I used 0.05 because you need to change the percent to a decimal, and 1 for n because it is compounded annually, meaning once a year.
28y-16y simpy equals to 12y
3x - 5y = 7
2x + 3y = 11
multiply the first equation by 2 and the second by -3:-
6x - 10y = 14
-6x - 9y = -33 Adding these 2 equations we eliminate the term in x:-
-19y = -19
y = 1
Substtute y = 1 in the first equation:_
3x - 5(1) = 7
3x = 12
x = 4
Answer is x=4,y=1 Answer
Second system of equation:-s
Here one equation is linear and the other is quadratic so we substitute fro y in the quadratic:-
From second equation y = 10x - 38, so substituting:-
10x - 38 = x^2 - 4x - 17
Gotta go right now . Sorry
This expression is actually pretty easy to simplify. Since all of the actions taking place are either addition or subtraction, we can initiate the first step of removing all the parentheses/brackets from the expression.
m - {n - [p + (m + n - p)]}
simplifies to
m - n - p + m + n - p
Then, we can reorganize the expression so that like terms are next to each other, making it easier to combine the like terms, which will be the next step.
m + m - n + n - p - p
Then, we combine like terms, keeping careful watch over addition and subtaction signs.
2m - 2p
(The n's cancel out because one is negative and the other is positive)
m - {n - [p + (m + n - p)]} simplifies to 2m - 2p.
Hope that helped =)
