The problem is not shown clearly therefore i am not sure if my answer will be correct, but, this inequality is already solved. all this means is that y is more than or equal to 4.5 (meaning that y can be 4.5, 5, 6, 7, 8 and so own but never a number less than 4.5), the "I I" only mean that y will never be a negative.
1. y = 28
2. a = -5
3. solutions = one
According to my calculation 565.3 is greater.
