Order the following expressions by their values from least to greatest

Licemer1 [7]

Answer:

Step-by-step explanation:

a = -1

b = 2

c = 3

a + (-c) = -1 + (-3) = -4

Both numbers have same sign(-Ve).So add and the result will have the -Ve sign.

c - (-b) = c + b = 3 + 2 = 5

b = 2

Least to greatest: a +(-c) , b , c-(-b)

Determine if the specified linear transformation is (a) one-to-one and (b) onto. Justify your answer. T: , T()(,),

xz_007 [3.2K]

Answer:

C. T is not one-to-one because the standard matrix A has a free variable.

Step-by-step explanation:

Given

$T(x_1,x_2,x_3) = (x_1-5x_2+4x_3,x_2 - 6x_3)$

Required

Determine if it is linear or onto

Represent the above as a matrix.

$T(x_1,x_2,x_3) = \left[\begin{array}{ccc}1&-5&4\\0&1&-6\\0&0&0\end{array}\right] \left[\begin{array}{c}x_1&x_2&x_3\end{array}\right]$

From the above matrix, we observe that the matrix does not have a pivot in every column.

This means that the column are not linearly independent, & it has a free variable and as such T is not one-on-one
