Answer:

║Y *  * ║

║0 Y * ║

║0 0 Y║

║0 0 0║

Step-by-step explanation:

First, let's look at the information in the question:

The proof of the theorem proves that the columns, say, A and B must be independent.

In the matrix, there is linearity and the trivial solution would be [ 0, 0 , 0 , 0] for the matrix to exist. In other words, all the unknowns must be zero.

This establishes the fact that the matrix T needs to be independent for the matrix function, say T (x) to be one-to-one.

By definition, one-to-one is ker (T) = {0}

Thus, the null space is occupied only by the zero vector.

Note: if there was no linear independence in the vectors, the solution would not be zero in the vector.

What is the range of g(x) = 3|x − 1| − 1? A. (-∞, 1] B. [-1, ∞) C. [1, ∞) D. (-∞, ∞)
AVprozaik [17]

Answer:

B. [-1, ∞).

Step-by-step explanation:

g(x) = 3|x − 1| − 1

When x = 1  g(x) = 3(0) - 1 = -1.

As all negative vales of x will give positive values of  |x - 1| then  g(x) = -1 is its minimum value. The graph will be shaped like a letter V with the vertex at (1,-1).

Therefore the range is  [-1, ∞).

One sixth of a right angle
QveST [7]
The answer will be fifteen degrees because one sixth is 1/6 and a right angle is 90 degrees so it will be 1/6 * 90/6 which will be 90 divided by 6 and equal fifteen .

Is 0.4 meter > 0.04 meter
Artemon [7]
Yes, it is. The reason is that 0.4 is equal to 0.40, which is greater than 0.04.

I WILL MARK YOU BRAINLIEST! IF YOU ARE GOOD WITH LINEAR EQUATIONS HELP ME PLEASE OR I WILL DIE!!!!!
USPshnik [31]

Answer:

Step-by-step explanation:

<em>1).</em> (40, 60)

m = 2

y - 60 = 2( x - 40 )

<em>2).</em> (5, - 1)

m = - 3

y - ( - 1) = - 3( x - 5 )

<em>3).</em> m = 2

y - 1 = 2( x + 2 )

y = 2x + 5
