zad 4 nie rozumiem i proszę o pomoc oraz rozwiązania dam naj :-)

a) [latex]y = h*x h-wspolczynnik[/latex] [latex]8 = h*2 h = 4[/latex] [latex]12 = 4*a a = 3[/latex] [latex]b = 4*9 b = 36[/latex] [latex]32 = 4*c c = 8[/latex] [latex]d = 4*40 d = 160[/latex] b) [latex]y = frac{h}{x} h-wspolczynnik[/latex] [latex]8 = frac{h}{2} h = 16[/latex] [latex]12 = frac{16}{s} 12s = 16 s = frac{16}{12} s = frac{4}{3}[/latex] [latex]t = frac{16}{9}[/latex] [latex]32 = frac{16}{u} 32u = 16 u = frac{16}{32} u = frac{1}{2}[/latex] [latex]w = frac{16}{40} w = frac{2}{5}[/latex]
