Answer:
B- Line Q
Step-by-step explanation:
Line Q is practically in the middle of the dots. It is called a trend line btw. :)
For this case we must find an expression equivalent to:

So:
We expanded
by moving 2 out of the logarithm:

By definition of logarithm properties we have to:
The logarithm of a product is equal to the sum of the logarithms of each factor:

The logarithm of a division is equal to the difference of logarithms of the numerator and denominator.

Then, rewriting the expression:

We apply distributive property:

Answer:
An equivalent expression is:

Concentric circles because if a line is tangent to one circle, it would only intersect teh other
The first amount would be the original amount as the answer because you are adding and then subtracting the same number. If the increase was 150% then the answer would be 50% more because 150%-100%=50%.
3.2 divided by 0.4 would be 8
