Timmy's bank account is $500 before going to vail. he then goes and buys skis and sees a -$500 on his bank statement indicating the purchase of the skis. what is the amount in his bank now? what does that represent?

Timmy has no amount left in the bank account after his skis purchase.

It represents that the cost of his ski was exactly equal to the amount in his savings.

Step-by-step explanation:

The total money in the account =  $500

The deduction in the account =  -$500

⇒ The Monet left in the account

=  Money in the Account  -  The deducted amount

= $500  -$500  = $0

So, Timmy has no amount left in the bank account after his skis purchase.

It represents that the cost of his ski was exactly equal to the amount in his savings.

And after its purchase, he has no money left in his account.

the answer is the third / last answer

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
