A car travel 35 miles on 3 gallons of gasoline. How many gallons of gasoline will the car need to travel 150 miles?

12.857

Step-by-step explanation:

. you divide 3 by 35 in order to find out how many gallons are used in a mile

. then multiply the number you get by 150 because the number you get is equal to 1 mile and u are finding for 150 miles

. lastly you round your answer (optional) ( i rounded to 3 dp's)

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.
