sqrt(-49) / [ (7-2i) - (4+9i) ]
= 7i / (3 - 11i)
= 7i (3+11i) / [ (3 - 11i) (3 + 11i) ]
= (21 i - 77) / (9 + 121) = choice (d), (-77 + 21i) / 130
g(x) is the translation 9 units up of f(x) = |x|

Given :
The function f(x)=|x|
we need to translate f(x) , 9 units up to get g(x)
g(x) is the translation 9 units up of f(x)
when graph of f(x) is translated 9 units up , then we add 9 at the end
If f(x)=|x| is translated 'a' units up then its becomes |x|+a
g(x) is the translation 9 units up of f(x) = |x|
So , 
Write the answer in the given form a|x-h|+k

Answer:
Solution given:
total no of girls [g]=25
let no of boys [b]=b
according to the question
g=2b+3
25-3=2b
b=22/2
b=11
<u>total number of boys going to Hershey Park is 11</u><u>.</u>
For some reason, you're not letting us see the choices,
so I can only give you a most general answer:
-- Any positive fraction greater than 1/2 is closer to 1 than it is to 0 .
-- No negative fraction is.
