Plane averaged 88mph with the wind and 44 against the wind. the average of these two averages is 66 mph. plane speed in still air is 66 and the wind speed was 22 (88-22=66 and 44+22=66)

Answer:
D. The oldest is 92 youngest 49
Step-by-step explanation:
we can get the answer by pairing each of the values on the left hand side that is these values 4 5 6 7 9 with values on the right.
the first age from the top row is 49 the second is 49
from the second row it is 50 50 51 51 52 5 59
from the 3rd row 61 62 63 64 64 65 6
from the forth row t s 71 72 73 73 74 75 7
from the fifth row it is 80 81 83 87
from the sxth row it is 91 92.
each of the numbers have just written out represents age. the oldest age there is 92 whle the youngest s 49. It is simply each number under attorney paired wth stem to make a number.

Answer:
-7/4
Step-by-step explanation:
You are looking for the composite g(f(2)). The simplest way to solve this is to evaluate f(2) and enter the solution in to your g function.
g(f(2))=g(-(2)^2-2(2)+4)=g(-4-4+4)=g(-4)
g(-4)=4/(-4(-4)-2)=4/(16-2)=4/14=2/7
Therfor, g(f(2))=2/7 **I'm assuming the -4x-2 is all in the denominator of the g(x) function. If -2 is not in the denominator you would have
g(f(2))=4/(-4(-4)) -2=4/16 -2=1/4 -2=1/4-8/4= -7/4
