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.

The way you get this is 2 divide by 25 then, multiply that number by 19.49

The word "difference" means "subtract" so B. Wouldn't be B. Because it's adding. This leaves us with A,C, and D
For A. It's a positive one (so this can't be your answer)
For D the negative one is in the front
The question isn't asking the different -1 and -12
So, this leaves us with option C as your answer
Good luck on your assignment and enjoy your day!
