Answer 2

Пошаговое объяснение:

$- 3 - 6 |7 - 7| = - 3 - 6 \times 0 = - 3$

Answer 3

To evaluate the expression $3x - 6|y - 7|$ when $x = -1$ and $y = 7$, substitute these values into the expression:

$3(-1) - 6|7 - 7|$

Now, let's simplify step by step:

1. $3(-1)$ equals $-3$:

$= -3 - 6|7 - 7|$

2. $7 - 7$ equals $0$, so $|7 - 7| = |0| = 0$:

$= -3 - 6 \times 0$

3. $6 \times 0$ equals $0$:

$= -3 - 0$

4. Finally, $-3 - 0$ equals $-3$:

$= -3$

So, when $x = -1$ and $y = 7$, the value of $3x - 6|y - 7|$ is $-3$.
