Plz Help!!!! <br>Solve for x<br>3y = 4x+ 1

astraxan [27]

Answer:

Step-by-step explanation:

STEPS FOR SOLVING LINEAR EQUATION

3y=4x+1

Swap sides so that all variable terms are on the left hand side.

4x+1=3y

Subtract 1 from both sides.

4x=3y−1

Divide both sides by 4.

3y−1

Dividing by 4 undoes the multiplication by 4.

3y−1

Please find the square roots of the following complex number.

Nana76 [90]

Hey there,

First, find the square root of the given equation.

$\sqrt{z}=\sqrt{81(\text{cos}(\frac{4\pi}{9})+i\text{sin}(\frac{4\pi}{9})}\\=9\text{cos}\frac{1}{2}(2k\pi+(\frac{4\pi}{9}))+i\text{sin}\frac{1}{2} (2k\pi+(\frac{4\pi}{9}))$

Keep in mind that this is solved for k = 0 and 1.

Second, simplify.

$=9\text{cos}(\frac{2\pi}{9})+i\text{sin}(\frac{2\pi}{9})~\text{or}~9\text{cos}(\frac{11\pi}{9})+i\text{sin}(\frac{11\pi}{9})$

Best of Luck!
