Question

а сколько будет 2 / 5 - 3/4 модуль X + 1/3 при -5/3​

Answer 1

$\frac{2}{5} - \frac{3}{4} |x| + \frac{1}{3} = \frac{6 + 5}{15} - \frac{3}{4} |x| = \frac{11}{15} - \frac{3}{4} |x| = \frac{11}{ 15} - \frac{3}{4} | - \frac{5}{3} | = \frac{11}{15} - \frac{3 \times 5}{4 \times 3} = \frac{11}{15} - \frac{5}{4} = \frac{44 - 75}{60} = - \frac{31}{60}$
