Question

Пожалуйста только 5!!!

Answer 1

1) Г

$y = {x}^{2} - 25 \\ {x}^{2} - 25 = 0 \\ (x - 5)(x + 5) = 0 \\ x _{1} = 5 \\ x _{2} = - 5$

2) Б

$y = 4x + 16 \\ 4x + 16 = 0 \\ 4x = - 16 \\ x = - 16 \div 4 \\ x = - 4$

3) Д

$y = 8 - x \\ 8 - x = 0 \\ x = 8$

4) А

$y = \frac{2}{x} + 10 \\ \frac{2}{x} + 10 = 0 \\ \frac{2}{x} = - 10 \\ x = 2 \div ( - 10) \\ x = - 0.2$
