X^2 - xy + xy - Y^2
=
X^2 - Y^2
Answer: No Solution
Step-by-step explanation:
y=2x+1 and 2x-y=3
Substitute y=2x+1 into 2x-y=3
So you will have: 2x-2x+1=3
Then,
2x-2x=0
0+1=3
1=3
1 doesn't equal 3 so there is no solution.
I don’t really know but I want to answer so I can get the account to 100%
Answer:
So, there are 3 cards in total, which means your pobability of picking one card out of the 3 cards is %33.33. So the probability of picking a 7 is 1/3. Because the other two numbers are greater than 7, and you already picked 7 so you cannot pick it again, the probabitily of pick a number greater than 7 is %100, or 3/3.
I hope that answers your question! :)
Y = 2x - 4
You need to take everything except y to the LHS to get the equation into the form of y = mx + c
