Answer:


Step-by-step explanation:
Given
Two integers a and b
The first statement in the question says, their sum is at least 30
The keyword "at least" means their sum can not fall below 30 and this is represented mathematically as

The next statement says their difference is at least 10 and b is greater;
The keyword "at least" means the same as used above (i.e. can not exceed); The second statement is represented as:

Hence, the system of inequality that represents the statements are:


Relationship 1: y1 = x + 3
Relationship 2: y2 = 3x^2
Relationship 3: y3 = 3^x
