9. What command allows you to permanently move a text from one document to another?

crtrl c on the old doc and crtrl v on the new doc

I think it's the cut and paste

Explanation:

The user selects or "highlights" the text or file for moving by some method, typically by dragging over the text or file name with the pointing-device or holding down the Shift key while using the arrow keys to move the text cursor.

The user performs a "cut" operation via key combination Ctrl+x menu, or other means.

Visibly, "cut" text immediately disappears from its location. "Cut" files typically change color to indicate that they will be moved.

answer: a, c

divide any of the y values by x values and you will always get 3 is the most simple way i can put it for you.
