Question

Va rog mult, imi trebuie urgent​

Answer 1

$5 \leqslant x < 10$

=> x = {5, 6, 7, 8, 9}, deci C = {5, 6, 7, 8, 9}

$2y + 3 \leqslant 27$

$y \leqslant \frac{27 - 3}{2}$

$y \leqslant 12$

y aparține N* => y este diferit de 0

D = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

Răspuns corect: b)
