\[x - y = - 5;\ \ \ \ \ y = x + 5\]
\[при\ x = 5 \Longrightarrow \ y = 10\]
\[\text{\ \ \ \ \ \ \ \ }x = - 5 \Longrightarrow \ \ y = 0\]
\[при\ y = 5 \Longrightarrow \ \ x = 0\]
\[Ответ:в).\]
\[\boxed{\text{990.\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[y = x^{2} + 2x\]
\[y( - 1) = 1 - 2 = - 1;\text{\ \ }\]
\[y( - 0,5) = 0,25 - 1 = - 0,75;\text{\ \ }\]
\[y(0) = 0;\]
\[y(0,5) = 0,25 + 1 = 1,25;\ \]
\[y(1) = 1 + 2 = 3;\text{\ \ \ }\]
\[y(1,5) = 2,25 + 3 = 5,25;\]
\[y(2) = 4 + 4 = 8;\ \]
\[y(2,5) = 6,25 + 5 = 11,25\ \ \]
\[y(3) = 9 + 6 = 15\]
