-45x+72
you multiply the 9 by everything in the parentheses
The answer would be x=118.
Answer: A.
Step-by-step explanation: if you look close enough, you can see exactly how long it is, and see that it does also have the two arrows along with it, but it’s the exact same just tilted a little bit but trust me I believe he correct answer is A.
Answer:
2^n
Step-by-step explanation:
So whenever you flip a coin, you can see it as 2 nodes branching off of each existing node. so for example when you flip a coin once you're going to have 2 sequences initially H and T, now when you flip a coin again for each of those 2 sequences 2 are going to branch off of that, making the total sequences 4, and the next flip 2 sequences are going to branch off each of the 4 sequences and so on. this can generally be described as: 2^n
I attached an image describing this a bit better but the bottom line is that for each 'end node'/sequence you're going to have 2 branch off of it, thus for each coin flip the number of sequences multiplies by 2
Answer:
midpoint: (7.5, 1.5)
Step-by-step explanation:
midpoint formula: ( (x1 + x2)/2 , (y1 + y2)/2 )
x1= 10
x2= 5
y1=1
y2=2
( 10 + 5 )/2 = 7.5
( 1 + 2 )/2 = 1.5
midpoint coordinates => ( 7.5 , 1.5 )
