Answer:
Population
Step-by-step explanation:
If we know the root Demos means people and graphic means picture, let's put the english terms together.
Demo graphic
People graphic
So this is going to be a "People Graphic." So we know that Countries and Continents are ruled out.
Now I just used logic to figure out whether it's population or leaders. A map showing the leaders of something would be useless, but a map showing population is useful. So I assumed that a Demographic map shows population (I also looked it up to check, and yes this is right.)
Hope this helped!

Linear equations
Sometimes we need to know the value of a variable in a given equation and that variable is given as a polynomial of degree 1. Solving for that variable means isolating it and replacing the other known values
Steven was 7 years old eight and one-half years ago. If we call x as the actual age of Steven, his age eight and one-half years ago was
We know he was 7 years old then, so
We need to know his actual age, so let's solve for x, adding to each side of the equation
Simplifying
Steven is 15 and one half years old now
If you want to find the solutions for this you have to factor it. Since it's a second degree polynomial, you'll have 2 solutions. Factoring this using the quadratic formula, you'll get factors of (5x-8)(3x-4). Solving these for x you get x = 8/5 and x = 4/3.
