Answer:
exactly one, 0's, triangular matrix, product and 1.
Step-by-step explanation:
So, let us first fill in the gap in the question below. Note that the capitalized words are the words to be filled in the gap and the ones in brackets too.
"An elementary ntimesn scaling matrix with k on the diagonal is the same as the ntimesn identity matrix with EXACTLY ONE of the (0's) replaced with some number k. This means it is TRIANGULAR MATRIX, and so its determinant is the PRODUCT of its diagonal entries. Thus, the determinant of an elementary scaling matrix with k on the diagonal is (1).
Here, one of the zeros in the identity matrix will surely be replaced by one. That is to say, the determinants = 1 × 1 × 1 => 1. Thus, it is a a triangular matrix.
For the first equation, I put it in y=mx+b form, so y=-3x-9
the second one is x=4
hope i helped
Accounting is an action of financial accounts, the target audience is people who want to major in business/accounting.
Answer:
Below.
Step-by-step explanation:
So calculate.
-1/6x+3+1/3x+1=x+4.
Cancel equal terms.
-1/6x+4+1/3x=x+4
Multiply both sides -1/6x+1/3x=x
collect like terms.
-x+2x=6x
move the variable from right to left.
x=6x
collect like terms
x-6x=0
Divide both sides
-5x=0
x=0
