Answer : B! As you can see, you can go to the x axis, and go to number 4. Then go down to -2, and you will end up in point B!
20/x+11=10/x+3
20(x+3)=10(x+11)
20x + 60 = 10x + 110
10x = 50
x = 5
2x + 40
Divide both sides by 2
You get x + 20
If the base were 1, then the final value would never change...it would be a constant...
If the base is between zero and one, it is an exponential decay equation, so the final value would continually get smaller and smaller...
