Functional style: output two functions as a single function

I have two functions: one of which generates a number and the other an image. What I would like to do is create a single function that produces both the number and the image.

As MWE, take the following:

Tri = Triangle({{0, 0}, {0, 1}, {1, 0}})
PictureTest(x_, y_, z_) := 
RegionPlot(x >= z*y && {x, y} (Element) Tri, {x, 0, 1}, {y, 0, 1})
MinTest(x_, y_, z_) := Minimize({x, x >= y + z && {x, y} (Element) Tri}, {x, y})

I would like to create a new NewFunc (x_, y_) function that results in both PictureTest (x, y, z) and MinTest (x, y, z). (Or even better if you add some words and give it PictureTest (x, y, z) and "the minimum is MinTest (x, y, z)").

(This may seem silly given the specific functions above. But I am working with more complicated functions and z is, in fact, many variables. So, in practice, I would like to enter "z" once and get the answer to both PictureTest and MinText I imagine the answer is in the Mathematica documentation, but I don't know what I'm looking for, I'm not even sure if I'm using the correct tags.)
