Kevin lunch account has started balance of $20. The table shows the remaining balance after certain number of days. If Kevin is bringing his lunch school but find a sports drink from the cafeteria each day, how much does the sport drink cost? use the slope= y2-y1/x2-x1

answer: the common difference is -0.10

sine

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.
