Answer:
-4
Step-by-step explanation:
whatever is inside the vertical lines becomes positive
vertical lines mean “the absolute value of that expression”
number inside the vertical lines mean how far the number is from 0
absolute value can be 0 or positive but never negative
but a negative in front of the vertical lines means
-1 times absolute value of that number
-|-7 + 3| =
-|-4| =
-1 times |-4| =

Answer:
option D
2x4; -11
Step-by-step explanation:
Order of matrix is in form (m x n), here m is the row and n is the column of the matrix.
So this matrix have 2 rows and 4 columns
1)Order of matrix
2x4
2)
here 1 is the row and 2 is the column
-11
Each elements of the matrix can be identity as below
Let the first number be x.
Therefore second number is (x+2).
Therefore third number is (x+4).
Therefore forth number is (x+6).
Hence,
(x+x+2+x+4+x+6+x+8)/4 = 15
(4x+12)/4 = 15
x+3 = 15
x = 12
So,
The number is 12, 14, 16, 18.
Hope it helps : )
