In June 1983, one other person and I on a flight to London, saw the underground city about two to three hours West of Heathrow Airport. As I recall it was about 3 or 4 Oclock in the afternoon, and a very bright sunny day. The pilot had started decending from the higher altitude. I have contacted many individual and companies through the years, and no one seem to have any idea what we saw. I am serious, and this is not a prank or joke. I really appreciate those who are sincere in trying to help solve this mystery for me.

For Tax purposes, rental houses are linearly depreciated over twenty seven and one half years. What would be a $110,000 house be worth after 3 years? (Hint: t= time of depreciation and V= value. Identify two points (t,V) and use them to construct a linear equation. Then compute V when t=3.

Answer choices are as follows:
$82,500
$98,000
$101,977
$107,000


All I know is that this is a linear equation. I don't understand what the "t" and the "V" are and how they are supposed to help me. Please show work.

And what is a rough formula in which an average person can do it? For example, right now the Japanese population is 127.5 million and in 2050 they predict it will be 104 million, and there are 1.4 children born per woman, and to sustain the population it must be 2.1. What other information did the demographer use and how can an average person attempt to predict the future population?

We are working on parallel and perpendicular linear functions.

The question I have trouble with is as follows:
Are the lines perpendicular? Parallel? Neither?

9) y = 5x - 7; y = 5x + 8

I know we can use the formula of y = mx + b, but how can I use this formula if I don't know what to substitute?

***Please do not give me the answer to the problem, just where I need to begin on it.***


Thanks!
