Answer: the integers are closed under addition, multiplication, and subtraction, but NOT division.
Step-by-step explanation:
The answer is x=3 next time when you are use x^2 when asking too the second power
18, 6, 13
because if you add 2 sides should be > other side
18+6>13
18+13>6

13+6>18 </span>
Answer:
Account balance is not proportional to the number of weeks.
Step-by-step explanation:
Initially Adrian's saving account balance was = $28
He deposits $15 in his account each week.
If we denote week with a variable 'x' then after 'x' weeks total amount in is account = $15x
So, total amount in his account after 'x' week will be;
y = 15x + 28
It's a linear equation representing total amount after 'x' weeks with a constant growth rate of 15 and initial amount 28.
In other words equation is in the form of y = mx +b.
This equation doesn't show the proportional relation because equation in the form of y = kx represents the relation of proportionality only.
