Jenny is saving $18 a week. She wants to buy a cell phone for $252. How many weeks does Jenny need
save for her cell phone?

14

Step-by-step explanation:

So what I did was divided 252 by 18 and got 14

I divided the money she needed by how much she gets every week and got 14 so that means it will take her 14 weeks to get her phone.

BAM! Hope it helps! :}

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.
