Lorena and benita are saving money. they began on the same day. lorena started with $30. each week she adds $14. the graph describes benita's savings plan.

which girl will have more money in 5 week? how much more will she have

Step-by-step explanation:

In 5 weeks, Lorena will have added 5×$14 = $70 to the $30 she started with. Her total will be $100.

Benita's total is $90 in week 5, as read from the graph.

Lorena has $10 more than Benita at week 5.

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.
