Apply the indicated operation to the matrix. i need help with one question, anyone pls? will mark brainliest!

C. 2  -2  -3

Step-by-step explanation:

this is a combination of indicated operations

the number on the left of the indicated operation is the original set  

the number '1/4' next to R shows that you need to multiply certain numbers by 1/4

the subscript on the R's shows which row the multiplication needs to be done on...

in this case it is saying that 1/4 + will become the new

so multiply 1/4 by a number in the row and then add that to the corresponding number from  

an example: (1/4 x 8) + 0 ------->  2

2 would be the new first number in the second row

where are the choices?
