Ton Which of the following best represents a proportional
relationship?
one:
John scored 8 points in 12 minutes and scored 15 points in 20
minutes.
A bird ate 20 seeds in 30 seconds and ate 15 seeds in 20 seconds.
A drone flew 50 feet in 10 seconds and flew 75 feet in 15 seconds.
A restaurant sells 3 desserts for $6.00 and sells 5 desserts for
$7.00

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

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.
