Let T be the linear transformation whose standard matrix is Aequals[Start 3 By 3 Matrix 1st Row 1st Column 1 2nd Column negative

Scilla [17]

Answer:

Yes the linear transformation is one to one and it maps a set of real numbers R cubed onto set of real numbers R cubed

Step-by-step explanation:

To show that the linear transformation is one to one, we must show that the columns are linearly independent columns (i.e it must have the trivial solution)

$A = \left[\begin{array}{cccc}1&-2&3&0\\-1&3&-4&0\\-5&-2&9&0\end{array}\right]$

For the Augumented matrix A and applying Row Reduction Formula we have that

= $\left[\begin{array}{cccc}1&-2&3&0\\0&1&-1&0\\0&0&-18&0\end{array}\right]$

we can deductively see that $x_{3} = 0, x_{2} = 0, x_{1} = 0$

Since the columns are linearly independent, Hence it is a one-to-one transformation and it maps a set of real numbers R cubed onto set of real numbers R cubed

Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x.

364 = 1.40x

Solving for x gives x = 260.

Thus, the autograph of the basketball player was worth only $260 last year.
