Answer:
Answer 1
i) 122 (123 is an odd number and hence the machine will subtract 1 from 123, i.e. 123 - 1 = 122)
ii) +72 or only 72 (-72 is a negative number and hence, the machine will produce the additive inverse of -72 i.e. +72)
Answer 2
Option d) All of the above
Reason:-
Option a) 36 is an even number, thus when put into the machine, it will divide it by 2 to get 18
Option b) 19 is an odd number which when put into the machine, it will subtract 1 from it to give 19 - 1 = 18.
Option c) -18 is a negative number, which when put into the machine will produce its additive inverse i.e. +18 or only 18.
Therefore, the inputs of options a, b and c would produce the same output, hence Option d is the correct answer.
Answer 3 (Refer to Answer 2 for the processes)
a) -24 ——› b) 24 ——› c) 12 ——› d) 6 ——› e) 3 ——› f) 2 ——› g) 1 ——› h) 0
a to b) -24+24 = 0
b to c) 24 ÷ 2 = 12
c to d) 12 ÷ 2 = 6
d to e) 6 ÷ 2 = 3
e to f) 3 - 1 = 2
f to g) 2 ÷ 2 = 1
g to h) 1 - 1 = 0 ----------› Final answer
Hope this helped you, cheers ;)
