Help please (I have to write something here, so I will write this).

Solve the system of equations. 2x-2y=-4 and x+y=8. show work

The graph of f(x), shown below, has the same shape as the graph of g(x)=x^2,but is shifted up 2 unit. what is the new equation?

Gas is being pumped into a tank the total amount of gas g after amount of time t is given by the equation g= 50+20t if the total amount of gas that will fit into tank is 850 gallons how much time will take to fill the tank
