PLEASE HELP!! When solving equations containing rational expressions, which of the following is a true statement?

A. The multiplication property of equality only applies to equations where the rational expressions are identical.

B. The solution to an equation with rational expressions must be a rational expression.

C. There is no need to check the solution to an equation with rational expressions since it is guaranteed to be right.

D. The addition property of equality applies to equations with rational expressions.

D.The addition property of equality applies to equations with rational expressions.

Step-by-step explanation:

a=r

d=q

c=p

b=s

hope this !

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.
