Answer:

-9

Step-by-step explanation:

The problem can be easily solved if you know your cube table. Because by knowing that, you know that 9³ is 729, meaning that -9³ would be -729.

Without knowing your cube tables, you can do -9 x -9 x -9 = -729.

Since -9 x -9 = 81, you can use a calcuator or solve on paper for 81 x -729.

DedPeter [7]

By plugging (k-2) in t, we can write that

$\dfrac{b}{-3}\geq6\\\\\\\dfrac{b}{-3}(-3)\geq6(-3)\\\\\\\large\boxed{b\leq-18}$
