Answer:
x=1,y=3
correct answer is (1,3)
Step-by-step explanation:
We can quickly eliminate y by subtracting one equation from the other
(-2x+y=1)-(-4x+y=-1)
2x=2
x=1
plug x=1 into equation 1
-2(1)+y=1
y=1+2=3
Answer:
True
Step-by-step explanation:
Answer:
60%
Step-by-step explanation:
There is a one in two chance of picking up a green ticket, since there are only two colours. The only number greater than 4 in this pack is 5. The chances of picking up a five are 2 out of 10. The chances of picking up a green 5 is 1 out of 10.
These events aren't mutually exclusive, because you can pick up a green 5 , which would constitute both events.
The probability of an OR function of events which aren't mutually exclusive is as follows:
Where:
A: green card
B: number 5 card
C: number 5 green card.
Thus:
