Which matrix is the product of a 3 × 3 identity matrix and the scalar 3?
Ludmilka [50]

Answer:

\left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right]

Step-by-step explanation:

In order to find out the resulting matrix, we will have to multiply the identity matric and the scalar 3:

The 3x3 identity matrix is:

\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]

Multiplying with scalar 3:

3\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]

The scalar will be multiplied by each element of the matrix.

Multiplying zeros with scalar 3 will give us zero. So the resulting matrix will be:

\left[\begin{array}{ccc}3*1&0&0\\0&3*1&0\\0&0&3*1\end{array}\right] = \left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right]

So the resultant matrix will be a scalar matrix with 3 at diagonal positions..

How many solutions a system of linear equations have if: Questions. 1.the equations have different slopes? 2.the equations have
KATRIN_1 [288]

Answer:

see below

Step-by-step explanation:

1.the equations have different slopes?  They will intersect at one point so one solution

2.the equations have the same slope and different y-intercepts.  They are parallel lines with a different y intercept so they will never intersect - no solutions

3.the equations have the same slope and same y-intercepts. they are the same line so they have infinite solutions
