Solution-
First 9 letters of alphabet are- A,B,C,D,E,F,G,H,I
Total number of ways of selection of 4 letters from 9 alphabets = 9C4
=9!÷((4!).(9-4)!) = 9!÷(4!×5!) = (9×8×7×6)÷(24) = 126
The number of ways of arranging these 4 numbers = 4! = 24
∴ Total number of possible permutations = 9C4×4! = 126×24 = 3024
∴ option number 2 is correct.
Answer:
it's about 18 percent decrease**** so 20 percent to round up
Step-by-step explanation:
Answer: f(x)-g(x)=2x+5
Step by step:
f(x) = 3x+2
g(x) = x-3
f(x)-g(x) = 3x +2 - (x-3) = 3x + 2-x+3=2x+5
Answer:
174

58*3
Answer:
9/5
Step-by-step explanation:
The slope between the two points can be found by ...
m = (y2 -y1)/(x2 -x1)
m = (-16-2)/(-10-0) = -18/-10
m = 9/5
The slope of the line is 9/5. Perhaps this is a match to choice A.
