Question 81801: I need to see if I did this right....I was asked to find the zero of the linear function.
F(x)=5x+20
5x+20=0
5x+20-20=0-20
5x/5=-20/5
x=-4
Did I do that right????
Thanks!!

You can put this solution on YOUR website!
Yes, you did it right.
You could prove that to yourself by substituting your answer value
into the original problem to see if you get a true statement.
