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

15. -2 (a - 4) = 13​
iogann1982 [59]

Answer:

a=-22

Step-by-step explanation:

Multiply both sides of the negative equation by (-2) to get the equation:

a-4=13(-2)

then simplify to get:

a-4=-26

then isolate the variable by addig 4 to both sides of the equation to get:

a=-26+4

simplify to get:

a=-22

HALP ME PLSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
Ne4ueva [31]

Answer:

x = -\frac{1}{3}, y = 2

Step-by-step explanation:

3x + 3y - 7 = 12x + y

6y - 12x - 1 = -45x

(3x - 12x) + (3y - y) = 7

(-12x + 45x) + 6y = 1

-3(-9x + 2y = 7)

33x + 6y = 1

27x - 6y = -21

33x + 6y = 1

60x = -20 -> x = -20/60 = -1/3

-9x + 2y = 7 -> y = \frac{7+9x}{2} = \frac{7+9*-\frac{1}{3}}{2} = 2
