A matrix with 5 columns and 6 rows added to another matrix with 5 columns and 6
rows would result in a matrix with:
A. 12 columns and 10 rows B.5 columns and 6 rows. C 10 columns and 12 rows. D. 6 columns and 5 rows

Option B - 5 columns and 6 rows is the correct answer

Step-by-step explanation:

Step 1 :

Given,

Number of columns of first matrix = 5

Number of rows of  first matrix = 6

Number of columns of second matrix = 5

Number of rows of  second matrix = 6

We need to determine number of rows and columns of the resultant matrix.

Step 2 :

When  a matrix of dimension m × n is added to another m × n matrix, the resultant matrix is also a m × n matrix.

Hence when a matrix with 5 columns and 6 rows added to another matrix with 5 columns and 6  rows the resultant matrix will also have 5 columns and 6 rows.

Step 3 :

Answer :

Option B - 5 columns and 6 rows is the correct answer

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
