Step-by-step explanation:
A) Popular novels from the past often ask provocative questions that are important to consider today.
In this speech, President Reagan uses the ending of a popular novel of the '60s to help pose his question about whether history still has a place for America, her people and her ideals. He takes provocative questions written in an old novel and uses them to show important subjects that need to be addressed today.
B) Many Americans have given up and say that the nation is no longer great or a land of dreams.
In his speech Reagan states that many Americans have lost their faith in their country and no longer believe that it is a place for dreams and greatness. This people say that Americans must "cut our expectations, conserve and withdraw"
C) President Reagan believed that John Wayne would argue that he was not the last American hero, because there are many more.

Answer:
[2 5 0]
[-7 -11/2 12]
Step-by-step explanation:
We want to perform elementary row operation represented by R2 - ½R1 on matrix A in the figure attached.
Now, matrix A is given as;
[2 5 0]
[-6 -3 12]
Now, R1 is row 1 = [2 5 0]
R2 is row 2 = [-6 -3 12]
Thus, R2 - ½R1 = [-6 -3 12] - ½[2 5 0]
This gives;
[-6 -3 12] - [1 5/2 0] = [-7 -11/2 12]
Now,[-7 -11/2 12] will be the new row 2 since it's just an elementary row operation we did on the Matrix A.
Thus, the new matrix is now;
[2 5 0]
[-7 -11/2 12]
