F ( x ) = ( x - 1 ) / 2
y = ( x - 1 ) / 2
x - 1 = 2 y
x = 2 y + 1
f ^(-1) ( x ) = 2 x + 1 ( this is inverse function )
f ^(-1) ( 5 ) = 2 * 5 + 1 = 10 + 1 = 11
Answer: C ) 11
I hope this helps! its in the file below!
X=x-9.
Subtract x from both sides of the equation
0=-9
Because this is false, there are 0 solutions.
Final answer: A
Answer:
you would go to the left of zero 2 spaces to -2 then go 6 to the right of -2 to number 4 because -2 -(-6) = 4
Step-by-step explanation:
Assuming the probability of a boy is 50%, then the probability of 5 boys is
(50%)(50%)(50%)(50%)(50%) = 3.125%.
(1/2)(1/2)(1/2)(1/2)(1/2) = 1/32
