In cryptography, inverse functions are used by government agencies and other
businesses to encode and decode information. the alphabet is a = 1, b = 2, c = 3,
if the encoding function is y = 3x + 4 and the code numbers are 43, 7, 25, and
19, what is the encoded word? (find the y values of the inverse.)

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

your answer   is c
