Answer:
Attachment is correct graph.
Step-by-step explanation:
We are given a equation of line y=|x|
It is absolute function which gives always positive value.
It's vertex at (0,0). This function will break at (0,0)
It is linear equality.
So, function is break at point x=0
Now we make tale of x and y
x y
-3 3
-2 2
-1 1
0 0
1 1
2 2
3 3
Now we plot the point on graph and join the points to get graph.
Please see the attachment for correct graph.
Answer:
30
Step-by-step explanation:
To find the determinant of a 3x3 matrix, you can use this method. (See picture.)
Start with the first number in the top row, and block off the row and column. A 2x2 matrix will be left. Find the determinant of this 2x2 matrix, and multiply it by the number in the top row.
Repeat for the other two numbers in the top row. Add the first result, subtract the second, and add the third.
det A = -2 [(3)(-5) − (a)(0)] − 2 [(0)(-5) − (a)(0)] + b [(0)(0) − (3)(0)]
det A = -2 (3)(-5) − 0 + 0
det A = 30
