By de Moivre's theorem,
![\implies \sqrt[4]{(1 - i)^2} = \sqrt[4]{2}\,e^{i(2\pi k-\pi/2)/4} = \sqrt[4]{2}\,e^{i(4k-1)\pi/8}](https://tex.z-dn.net/?f=%5Cimplies%20%5Csqrt%5B4%5D%7B%281%20-%20i%29%5E2%7D%20%3D%20%5Csqrt%5B4%5D%7B2%7D%5C%2Ce%5E%7Bi%282%5Cpi%20k-%5Cpi%2F2%29%2F4%7D%20%3D%20%5Csqrt%5B4%5D%7B2%7D%5C%2Ce%5E%7Bi%284k-1%29%5Cpi%2F8%7D)

We are asked to transform the given equation into slope intercept form. The given expression is 2-3y+6x=0. To do this, we need to remember the slope-intercept form is below:
y = mx + b where "m" represents the slope and "b" represents the y-intercept
The solution of the problem is shown below:
2 - 3y + 6x = 0 ,transpose -3y to the opposite side such as:
2 + 6x = 3y , re-arranging the given we have:
3y = 6x + 2 , divide both sides by 3 such as:
3y/3 = (6x +2) / 3
y = 2x + 2/3 where m = 2 and b = 2/3
The answer is y = 2x + 2/3.
Answer:
51
Step-by-step explanation:
Answer:
Width=5 Length=10
Step-by-step explanation:
Because we find perimeter by Length + Width x 2, in order to find out the width and the length, we need to remove x2. After that, we get fifteen because we divided thirty by 2. We then need to divide 15 by 3 because we need 1/3 of 15 (whatever that may be) for the width and the we need double of the width for the length which would be 2/3. 1/3 of 15 =5. When you double that, you get 10 for length. So width=5 and Length=10.
.87 is correct you can always check your work with an online calculator. :)
