Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically. (4 points and these are my equations y=(1.2)^x ( Neighborhood A) y=40+3x ( Neighborhood B) now when is it the same?

An easy way to do this would be to plug in the number of years in x, and see if they gave you the same number

Your first equation should be \[y=30(1.2)^x\]

Yes it maybe hard to do without a graph, so here is the graph, the point where it's the same is the intersection |dw:1435973442483:dw| :)

Hey, just go on this site and plug in the equation as I have on the left, I think if you see for yourself it will be much clearer https://www.desmos.com/calculator

It would be annoying to equate them as well haha

in case you need to test your algebra skills on logarithmic and and linear equations, this would be a good problem to solve for intersection (value of x and y)

Actually it's not too bad, would require you to know your exponent rules though

\[30\left( \frac{ 2^2 \times 3 }{ 2 \times 5 } \right)^2 = 40+x...\] etc
