Answer:
Option c, A square matrix
Step-by-step explanation:
Given system of linear equations are



Now to find the type of matrix can be formed by using this system
of equations
From the given system of linear equations we can form a matrix
Let A be a matrix
A matrix can be written by
A=co-efficient of x of 1st linear equation co-efficient of y of 1st linear equation constant of 1st terms linear equation
co-efficient of x of 2st linear equation co-efficient of y of 2st linear equation constant of 2st terms linear equation
co-efficient of x of 3st linear equation co-efficient of y of 3st linear equation constant of 3st terms linear equation 
which is a
matrix.
Therefore A can be written as
A= ![\left[\begin{array}{lll}3&-2&-2\\7&3&26\\-1&-11&46\end{array}\right] 3\times 3](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Blll%7D3%26-2%26-2%5C%5C7%263%2626%5C%5C-1%26-11%2646%5Cend%7Barray%7D%5Cright%5D%203%5Ctimes%203)
Matrix "A" is a
matrix so that it has 3 rows and 3 columns
A square matrix has equal rows and equal columns
Since matrix "A" has equal rows and columns Therefore it must be a square matrix
Therefore the given system of linear equation forms a square matrix
Answer:
its a line
Step-by-step explanation:
Answer:
Amount theta she is putting in Checking account is 2272.80
Step-by-step explanation:
Given:
Amount on check = 2941
Amount that he want in cash = 100
Amount she put in saving account = 20% of remaining after getting cash
Remaining Amount she put in checking account.
To find: Amount in her Checking Account.
Amount left after taking cash = 2941 - 100 = 2841
Amount that she put in saving account = 20% of 2841 =
= 568.20
Amount in her checking account = 2941 - 100 - 568.20 = 2272.8
Therefore, Amount theta she is putting in Checking account is 2272.80
