4. the population of bay village is 35,000 today. every year the population of bay village increases by
750 people.
a. write a linear model that represents the population of bay village x years from today.
y-people
y = 750x+3500
x=years
b. in approximately many years will the population of bay village exceed 50,000 people?
20 years
how do you get 20 years

d

step-by-step explanation:

d

a. is correct

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.
