x+2y=4 by cremers rule​

Do not comment if you aren’t going to . create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

The function f(x)= -(x+5)(x+1) is down. what is the range of the function?
