Muriel collects rainwater in a large barrel that weitghs 20 pounds. when there are 10 gallons of water in the barrel, the total weight of the barrel and the water is 103.4 pounds. When there are 20gallons of water, the total weight is 186.8 pounds. Which equation and graph match this situation

y = 8.34x + 20 <== this is ur equation with x being the number of gallons and y being total weight in lbs

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.

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
