Answer:
I believe that the owner of the dice is actually not lucky. There are people who practice throwing dice in a controlled way in order to get a specific side of the dice. If he practices his dice throwing a lot, then he would have a much higher chance of winning at a game of dice.
Step-by-step explanation:
Since you said he was lucky, I decided to make an answer saying that he wasn't lucky so you can choose between both of them. Your answer was good as well.
U minus them?or plus them?
Answer:
![8{x}^{2} - x - 8](https://tex.z-dn.net/?f=8%7Bx%7D%5E%7B2%7D%20%20-%20x%20%20%20-%208)
Step-by-step explanation:
We want to subtract
![- 2 {x}^{2} + 4x - 1](https://tex.z-dn.net/?f=%20-%202%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20-%201)
from
![6 {x}^{2} + 3x - 9](https://tex.z-dn.net/?f=6%20%7Bx%7D%5E%7B2%7D%20%20%2B%203x%20-%209)
We set up the subtracttion problem to get:
![6 {x}^{2} + 3x - 9 - ( - 2 {x}^{2} + 4x - 1)](https://tex.z-dn.net/?f=6%20%7Bx%7D%5E%7B2%7D%20%20%2B%203x%20-%209%20-%20%28%20-%202%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20-%201%29)
We expand the parenthesis to get:
![6 {x}^{2} + 3x - 9 + 2 {x}^{2} - 4x + 1](https://tex.z-dn.net/?f=6%20%7Bx%7D%5E%7B2%7D%20%20%2B%203x%20-%209%20%20%2B%202%20%7Bx%7D%5E%7B2%7D%20%20%20-%204x%20%20%2B%201)
Group similar terms:
![6 {x}^{2} + 2 {x}^{2} + 3x- 4x + 1 - 9](https://tex.z-dn.net/?f=6%20%7Bx%7D%5E%7B2%7D%20%20%20%2B%202%20%7Bx%7D%5E%7B2%7D%20%2B%203x-%204x%20%20%2B%201%20-%209)
We simplify to get:
![8{x}^{2} - x - 8](https://tex.z-dn.net/?f=8%7Bx%7D%5E%7B2%7D%20%20-%20x%20%20%20-%208)
36 divided by 3 plus 90 divided by 3 I think I hope this helps u
Answer: Look at the number of points where the graphs intersect each other...the points where the graphs of the functions cross each other are the solutions to the system.
Upon looking, you should see 4 points where the graphs intersect, so there are 4 solutions to the non-linear system of equations.
