The following input-output pairs have been observed during the operation of a linear system: x1(n) = f−1; 2; 1g ! t y1(n) = f1; 2; −1; 0; 1g x2(n) = f1; −1; −1g ! t y2(n) = f−1; 1; 0; 2g x3(n) = f0; 1; 1g ! t y3(n) = f1; 2; 1g a) suppose the input signal is x(n) = (n), what is the resulting output signal? b) determine whether the system is time-invariant. justify your answer.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
