Ann is buying a house that costs $250,000. She is making a down payment of 15 percent, and her closing costs will amount to 3 percent. Over the life of her loan, she will pay $282,089.89 in monthly payments. What is the total cost of her house?

Answers

BEFORE YOU PUT YOUR BLIND TRUST IN THIS ANSWER: I am not completely sure as to how house payments work, so I could be wrong about how I am calculating this...

15%= $37,500
3%= $7,500
monthly payments= $282,089.89
Original purchase price: $250,000

     250,000.00
-      37,500.00
+       7,500.00
+   282,089.89
---------------------
$   502,089.89

What is the domain of the function y=10-5x

Answers

Any real number (-inf, inf)
Domain of definition of a function is the set of numbers which the variable attains and for which the function is defined.

f(x) = sqrt (5x-10)

here x can have value equal to any real number >=2 because if x attains value less that 2, 5x-10 becomes negative and sqrt(5x-10) has no real value.

therefore the domain of the function f(x) is (2, infinity) inclusive of 2.

This trick is called the vertical line test. if you can scan the figure with a virtual line and it does not touch more than one side of the figure at one time then it is a function. if it touches more than one side or line of the figure it is not a function.
