Answer:
(h o k)(3) = 3
(k o h)(-4b) = -4b
Step-by-step explanation:
If f(x) and g(x) are inverses, then (f o g)(x) = (g o f)(x) = x
(h o k)(3) = 3
(k o h)(-4b) = -4b
Answer:
x^2-6x, 4x^2-1x,10x^2+8x,15x^2-3xy
Just use the distributive property like you have before and you will get these answers, Hope this helped!
Answer:
There is no question stated. If one assume the question is "Does the probability of picking the same color pen change after the first try?," the answer is "No."
Step-by-step explanation:
When the pen is replaced, the probability reverts back to the original value:
There are 7 pens:
5 Blue
2 Red
The probability of picking a red or blue pen on the first try is:
Red = 2/7
Blue = 5/7
When the pen is replaced, the probabilities return to the original values.
Answer:
8
Step-by-step explanation:
average is calculated as
average = 
= 13 ( multiply both sides by 2 )
sum of 2 eldest = 26
Then for the 4 children
average = 
= 
= 8
B,C and D are correct because all of those choices include letters which are arranged in order from left of right.
