Answer:
[2 5 0]
[-7 -11/2 12]
Step-by-step explanation:
We want to perform elementary row operation represented by R2 - ½R1 on matrix A in the figure attached.
Now, matrix A is given as;
[2 5 0]
[-6 -3 12]
Now, R1 is row 1 = [2 5 0]
R2 is row 2 = [-6 -3 12]
Thus, R2 - ½R1 = [-6 -3 12] - ½[2 5 0]
This gives;
[-6 -3 12] - [1 5/2 0] = [-7 -11/2 12]
Now,[-7 -11/2 12] will be the new row 2 since it's just an elementary row operation we did on the Matrix A.
Thus, the new matrix is now;
[2 5 0]
[-7 -11/2 12]
Answer:
Larger
Step-by-step explanation:
It will Be larger because a factor lower then 5 will make the dilatetion become smaller
8x+1=x-6
7x+1=-6
7x=-7
X=-1
Y=x
Y=-1
The simplified answer of 6/35 is 6/35. It is in simplest form.
M = 9
o = 7
m + 0 = 9 + 7 = 16
Hence, the answer is 16.
