These array of numbers shown above are called matrices. These are rectangular arrays of number that are arranged in columns and rows. It is mostly useful in solving a system of linear equations. For example, you have these equations
x+3y=5
2x+y=1
x+y=10
In matrix form that would be
![\left[\begin{array}{ccc}1&3&5\\2&1&1\\1&1&10\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%263%265%5C%5C2%261%261%5C%5C1%261%2610%5Cend%7Barray%7D%5Cright%5D%20)
where the first column are the coefficients of x, the second column the coefficients of y and the third column is the constants, When you multiple matrices, just multiply the same number on the same column number and the same row number. For this problem, the solution is
Answer:
The bank charged 56 dollars in interest
Answer:
(4, 0).
Step-by-step explanation:
y = 8x - 32
There are many solutions that we can choose from, since any set of coordinates that fit in the equation counts as a solution.
We can have (0, -32), (1, -24), (2, -16), (3, -8), (4, 0), and many more.
Hope this helps!

9 = hundreds
8 = tens
3 = ones
6 = tenths
2 = hundredths
5 = thousandths
You want to round to the nearest hundredths
Look at the number on the right, if it's bigger than 5, round up, if it's 4 or lower, round down.
In this case, the number to the right is a 5, so you round the 2 (hundredths) up one so:

Answer:
The answer is 113
Step-by-step explanation:
6^2 + 7(3^2 + 8 - 6)
36 + 7(9 + 8 - 6)
36 + 7(11)
36 + 77
113
