Can someone explain how to do this from step by step in order to get marked.

Step-by-step explanation:

First, convert the mixed fraction into an improper fraction:

Rewrite 2 as 2/1 and then cross-multiply to combine:

2.83941151 would be the answer you're looking for! : )

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.
