Answer:
3.2?? I am kinda confused
Step-by-step explanation:
Not sure what the correct description is but the answer is:
x <span>≥ 8</span>
I believe the answer is 9
This is because in order to take out a three, There would need to be 2 3's and 9 is 3x3, so the answer is 9.
A polyhedral is a shape that is flat and that has straight sides.
Answer: OPTION B.
Step-by-step explanation:
Given the following System of equations:
![\left \{ {{3x-5y=19} \atop {x+y=1}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B3x-5y%3D19%7D%20%5Catop%20%7Bx%2By%3D1%7D%7D%20%5Cright.)
You can use the Elimination Method to solve it. The steps are:
1. You can mutliply the second equation by -3.
2. Then you must add the equations.
3. Solve for the variable "y".
Then:
![\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B3x-5y%3D19%7D%20%5Catop%20%7B-3x-3y%3D-3%7D%7D%20%5Cright.%5C%5C.....................%5C%5C-8y%3D16%5C%5C%5C%5Cy%3D%5Cfrac%7B16%7D%7B-8%7D%5C%5C%5C%5Cy%3D-2)
4. Now that you know the value of the variable "y", you must substitute it into any original equation.
5. The final step is to solve for "x" in order to find its value.
Then:
![x+(-2)=1\\\\x=1+2\\\\x=3](https://tex.z-dn.net/?f=x%2B%28-2%29%3D1%5C%5C%5C%5Cx%3D1%2B2%5C%5C%5C%5Cx%3D3)
Therefore, the solution is:
![(3,-2)](https://tex.z-dn.net/?f=%283%2C-2%29)
