what do u want to do in here?
Multiply the first row by 1/2
r u trying to find the range?
No, all the problem says is to Perform the operation
"perform indicated row operations"------->does not include finding range all you have to do is multiply the elements in the first row of your matrix by 1/2
For the first row I got 6, 11, and 12
thats correct, and that all we can do in this case.
i thought she might wanted to find the range since i saw an R.....-_-
unless you are trying to row reduce it, or use gauss Jordan
its all good angela210793, i'll still give you a medal;)
Do I do the same with the second row?
you havent indicated what you wanted to do with the second row, all you wrote was 1/2R1, which means multiply row 1 by 1/2, if you want to do somehting with another row, you would have to indicate what you wanted to do with that row
D:but that's all the problem says.
the your done;) you have performed the indicated row operation
