<u>Matrix:</u> A matrix is a rectangular arrangement of numbers in the form of horizontal and vertical lines.
Horizontal lines are called rows and vertical lines are called columns.
<u>Order of Matrix:</u> A matrix containing x rows and y column has order x × y and it has xy elements.
<u>Different types of matrices:</u>
Row Matrix: This type of matrices have only 1 row. <u>Example:</u>
<u>Column Matrix:</u> This type of matrices have only 1 column. Example:
<u>Square Matrix:</u> In this type of matrix, number of rows and columns are equal. Example:
<u>Zero Matrix:</u> It is a matrix with all elements present is zero. Example:
<u>Identity Matrix:</u> In this type of matrix, diagonal element is 1 and remaining elements are zero. An Identity matrix is always a square matrix. Example:
3/4 multiplied by 3/10 gives a smaller product that 3/10 and 7/5 multiplied by 3/10 gives a larger product than 3/10
Answer:
n=-1
Step-by-step explanation:
First you add 5 to both sides an you would get -15n=15
Next divide by -15 on both sides and get n=-1
