Answer:
55600
Step-by-step explanation:
First times the number of possibilities of the amount of letters it could be so 26X26 as it is a non consecutive possibility that means both letters have the possibility to be the same. Then take the product of 26X26 and multiply it by the possibilities of the first number which is 10 then repeat that by again multiplying the product by 10 to represent the number of possibilities for the second number
(-1,2) is a solution
y>x
2>-1 is correct
in this case yes
x+y≥x
-1+2≥-1
1≥-1 is correct: Yes
in this case no
x+y≥y
1≥2
is not correct. No
