Solve the formula for the specified variable. a =  bh for b

Your goal is to get b alone on one side of the equals and get "not b" on the other. In this case, b and h are put together by multiplying. So we do the opposite operation - dividing, to get b and h separated.

A = b * h Put the multiplication operation in the original

A / h = (b * h ) / h Divide by h on both sides

A / h = b The h on the right side simplifies to 1

Thus b =

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.
