A group is working on finding the mass of an unknown substance. They are using a digital balance. The first time they take the measurement the balance reads “2.5g.” They try again and the balance reads “2.6g.” They take one final reading and balance reads “2.5g.” They find the mean mass by adding up the values and dividing by three (the number of measurements taken). Their final answer for the mass of the substance is 2.53g.

i dont know sorry

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.
