Which number line represents the solution set for the inequality 3x <-9?

1 answer:

7 0

We have the following inequality

$3x < -9$

First we simplify the inequality by dividing both sides by $-3$

$x < -3$

So $x\in(-\infty,-3)$ which means x is any number that is smaller than -3 non inclusive.

Hope this helps.

Reciprocals are technically flipped fractions. So it would be 10/9. 9 goes into ten one time, so it's 1 1/9.

You can factor -80 as

$-80 = (-1)\cdot 16 \cdot 5$

So, we have

$\sqrt{-80} = \sqrt{(-1)\cdot 16 \cdot 5}$

The square root of a product is the product of the square roots:

$\sqrt{-80} = \sqrt{(-1)}\sqrt{16}\sqrt{5}$

Since $i^2=-1$ and $4^2=16$ , we have

$\sqrt{-80} = 4i\sqrt{5}$
