Answer: The correct answer is - 12

Step-by-step explanation:

y = -5, z = 5 and w = -2

Inputing the various terms

-5 - (5 - (-2))

Resolving using BODMAS

= - 5 - (5+2)

= -5 - 7

= -12

Answer:

D.   (x - 2)(x + 2)

Step-by-step explanation:

Look at the graph, when y = 0, x = - 2 and x = 2, vertex = -4

OK so x = -2 means x + 2 = 0

and x = 2, means x - 2 = 0

So

answer :D.  (x - 2)(x + 2)

Suppose A is an m × n matrix in which m&gt; n. Suppose also that the rank of A equals n Show that A is one to one. Hint: If not,
rusak2 [61]

Step-by-step explanation:

If T:Rn→Rm is a linear transformation and if A is the standard matrix of T, then the following are equivalent:

 1.  T is one-to-one.

 2. T(x) = 0 has only the trivial solution x=0.

 3.  If A is the standard matrix of T, then the columns of A are linearly independent.

Here, A is a mxn matrix where m ≥ n and the rank of A equals n. It implies that the columns of A are linearly independent, for, otherwise, the rank of A would be less than n. Hence the linear transformation represented by A is one-to-one.
