Probability of selecting 2 nickels without replacement
This can be represented as: 
The solution is as follows
The second nickel is reduced by 1 because the first nickel was not replaced and this also reduces the total by 1
So, we have:
The line y = 3 means that x = 0.
The point (-3, y) tells me that x = -3 when y is 3.
So, y = 3 completes the point (-3, 3).
Answer:
21 and 96
Step-by-step explanation:
Let x and y be the two numbers such that x>y.
As the sum of both the numbers is 96.
x+y=96...(i)
As the larger number is nine less than four times the smaller number,
So, x=4y-9
From equation (i),
4y-9+y=96
5y=96+9=105
So, y=105/5=21
By using equation (i),
x=96-y=96-21=75
Hence, both the numbers are 21 and 96.
For this question you can say:
4f -3 +2g - 4g -2
so now you can simplify and find the answer:
4f -3 -2g -2 = 4f -2g -5
and that's the answer :)))
I hope this is helpful
have a nice day
