If you would like to write <span>(-3 + √-9)^2 in a standard form a + i * b, you can do this using the following steps:

</span>(-3 + √-9)^2 = (-3)^2 - 2 * 3 * √-9 + (<span>√-9)^2 = 9 - 6 * 3 * i - 9 = 0 - 18 * i = -18 * i
</span>
The correct result would be -18 * i.

Could someone give me an answer and explain how you got it ?
tankabanditka [31]

Answer:

A (9, 3)

Step-by-step explanation:

First the point is rotated 90° counterclockwise about the origin.  To do that transformation: (x, y) → (-y, x).

So S(-3, -5) becomes S'(5, -3).

Next, the point is translated +4 units in the x direction and +6 units in the y direction.

So S'(5, -3) becomes S"(9, 3).

Solve LaTeX: \frac{-x}{3} \:-15 x &gt; − 15 LaTeX: x\: \:-2
Fudgin [204]

Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

<h3>\frac{  - x}{3}  < 5</h3>

<u>First of all cross multiply</u>

That's

<h3>- x < 5 \times 3 \\  - x < 15</h3>

Next divide both sides by - 1 to make x positive and change the sign from < to >

That's

<h3>\frac{ - x}{ - 1}  <  \frac{ 15}{ - 1}</h3>

We have the final answer as

<h2>x >  - 15</h2>

Hope this helps you
