Answer:
![x=\frac{1}{2}\\\\y=-6](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B2%7D%5C%5C%5C%5Cy%3D-6)
Step-by-step explanation:
Given the following system of equations:
![\left \{ {{4x-11y=68} \atop {6x+5y=-27}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B4x-11y%3D68%7D%20%5Catop%20%7B6x%2B5y%3D-27%7D%7D%20%5Cright.)
In order to solve the system of equations using the Elimination Method, you can follow these steps:
- Multiply the first equation by -6 and the secondd equation by 4.
- Add both equations.
- Solve for "y".
Then:
![\left \{ {{-24x+66y=-408} \atop {24x+20y=-108}} \right\\.........................\\86y=300\\\\y=\frac{-516}{86}\\\\y=-6](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B-24x%2B66y%3D-408%7D%20%5Catop%20%7B24x%2B20y%3D-108%7D%7D%20%5Cright%5C%5C.........................%5C%5C86y%3D300%5C%5C%5C%5Cy%3D%5Cfrac%7B-516%7D%7B86%7D%5C%5C%5C%5Cy%3D-6)
- Substitute the value of "y" into one of the original equations and solve for "x":
![6x+5(-6)=-27\\\\6x=-27+30\\\\x=\frac{3}{6}\\\\x=\frac{1}{2}](https://tex.z-dn.net/?f=6x%2B5%28-6%29%3D-27%5C%5C%5C%5C6x%3D-27%2B30%5C%5C%5C%5Cx%3D%5Cfrac%7B3%7D%7B6%7D%5C%5C%5C%5Cx%3D%5Cfrac%7B1%7D%7B2%7D)

Answer: 5.733
Have a great day.
Answer:
the n(P) of P = {3, 5, 7, 11, 13, 17, 19} is "128".
Step-by-step explanation:
n(P) is the <u>Cardinality</u> of the set P. Its formula is 2^k.
where k = number of elements in the set.
