Niall owes $187 to his cousin. however, he doesn't have any money right now. he hopes to earn some money by painting a house. he gets paid $34 for every 2 hours he paints. which equation of a line models y, the amount of money he will have after paying back his cousin, in terms of x, the number of hours he spends painting?

where x>11

Step-by-step explanation:

Niall gets $34 for 2 hours.

So, he gets dollars per hour.

Now he owes $187 to his cousin.

Let the number of hours he works be = x

Let the money left with him after paying his cousin be = y

So, the equation forms:

Rather we can say it is :

where x>11

If we want to know how many hours are needed to pay the debt, we can consider y = 0

So, x = 11 hours

He needs 11 hours of work to pay back his cousin and after that all his earnings is 'y'. When x>11 then 'y' will have some money left.

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.
