I think you want to prove $E(f(X,Y)|X=x) = E(f(x,Y))$. This follows immediately from the independence of $X$ and $Y$. Let $f_{X,Y}(x,y)$ be the joint probability density function for $X$ and $Y$.

The given equations represent a pair of parallel lines (they do not intersect) and therefore there are not solutions. Explanation: Given [1] (XXX)x+8y = 7 ... If (−1,0) lies on the graph of y =f (x) , what is the point that lies on the graph of y =f (x+3) ... https://socratic.org/questions/589243fb7c01490182c4824e.
the main definitions and by listing several results which were proved in lectures (and Notes 3). Let X and Y be two discrete r.v.’s with a joint p.m.f. fX;Y(x;y) = P(X = x;Y = y). Remember that the distributions (or the p.m.f.’s) fX(x) = P(X = x) of X and fY(y) = P(Y = y) of Y are called the marginal distributions of the pare (X;Y) and ...
In this article, we will see the integration rules to be followed for solving an integral of the type e x [f(x) + f ’(x)], where f ’(x) is the derivative of f(x). We will use integration by parts and some other integration rules to solve these equations.

If F (x) = ⎡ ⎢ ⎣ cos x − sin x 0 sin x cos x 0 0 0 1 ⎤ ⎥ ⎦ then show that F (x). F (y) = F (x + y). Hence prove that [F (x)] − 1 = F (− x).
