Answer:
4\pm\sqrt{19}
Step-by-step explanation:
Move everything to left side
![x^{2} -8x -3 =0](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-8x%20-3%20%3D0)
Now to solve this square equation we need to find Descriminant
![D=b^{2} -4ac=64+12=76](https://tex.z-dn.net/?f=D%3Db%5E%7B2%7D%20-4ac%3D64%2B12%3D76)
As Descriminant D is greater than 0 then we have 2 solutions which we can calculate by this formula
![x_{1,2}=\frac{-b\pm\sqrt{D}}{2a} =\frac{8\pm2\sqrt{19}}{2}=4\pm\sqrt{19}](https://tex.z-dn.net/?f=x_%7B1%2C2%7D%3D%5Cfrac%7B-b%5Cpm%5Csqrt%7BD%7D%7D%7B2a%7D%20%3D%5Cfrac%7B8%5Cpm2%5Csqrt%7B19%7D%7D%7B2%7D%3D4%5Cpm%5Csqrt%7B19%7D)
Answer:
5%, 33%, 1/2, 75%
Step-by-step explanation:
5% , 33%, 75%, 1/2
Change 1/2 to a percent.
1/2 = 0.5 = 0.5 * 100% = 50%
We are comparing
5%, 33%, 75%, 50%
From least to greatest:
5%, 33%, 50%, 75%
Now we convert 50% back to a fraction.
5%, 33%, 1/2, 75%
There exists a similar question where m angle 2 is 9y + 4. If the angles are supplementary, the sum of their measures is 180 degrees. The equation that represents this situation is,
4y + 7 + 9y + 4 = 180
The value of y is equal to 13. The value of the measure of angle 2 is equal to 121 degrees.
To solve this, first make an equation:
![750(x)^{12}=1500](https://tex.z-dn.net/?f=750%28x%29%5E%7B12%7D%3D1500%20)
After you solve this, you get x = 1.0399, but we have to subtract 1 so we get 0.0399 which is
3.99%
