The TikZ/pgfplots parser gets confused about the brackets, it does not know which of them are delimiters of coordinates or expressions in the functions. So you have to help them a bit by adding curly brackets.
documentclass[tikz,border=3.14mm]standalone
usepackagepgfplots
pgfplotssetcompat=1.16
begindocument
begintikzpicture
beginaxis[xmin=0,xmax=1,ymin=0,ymax=1, samples=1000, xlabel=$c$,
ylabel=$s$,unbounded coords=discard]
addplot[blue, ultra thick] (x,(0.05*0.4+0.1*2*x)/(0.05+0.1*2));
addplot[red, ultra thick,domain=0:0.099] (-0.1/(2*10*(x - 0.1))+x,x);
addplot[red, ultra thick,domain=0.11:1] (-0.1/(2*10*(x - 0.1))+x,x);
endaxis
endtikzpicture
enddocument
Thank you! It's clear. Is there a way to remove the asymptote?

@Mark Sure. (Sorry, was offline.) I removed the red asymptote. If you want to remove the blue one as well, removeaddplot[blue, ultra thick] (x,(0.05*0.4+0.1*2*x)/(0.05+0.1*2));
. The red one was because you plotted over a singularity atx=0.1
, and one easy way to remove it is to add two separate plots that avoid it.
