Megan owes $46.40 for text messaging in the month of May. If her text messaging plan costs $11 for the first 250 messages and 20¢ for each additional text message, how many text messages did she send that month?

i would need to see the dot plot : )

u bout ugly as   a mf

step-by-step explanation: lol

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.
