It is worked out that if 5 ladles full of soup are given to

each person,

140 people can be fed.

The customers have complained in the past that the

portions are too small.

The cook decides to give 7 ladles full of soup to each

person.

How many people can now be fed soup?

people

26?

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.
