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.
<span>f(x) = 2x + 3
</span><span>g(x) = x²-7
</span>(f+g)(x) = f(x) + g(x) = 2x + 3 + x² - 7 = x² + 2x - 4
(f+g)(x) = x² + 2x - 4
