Answer:
I just googled it
Step-by-step explanation:
5
x
−
y
=
15
Add y to both sides of the equation.
5
x
=
15
+
y
Divide each term by 5 and simplify.
x=
3
+
y
5
<span>Let x = represent the number of weeks of deposits
A = 120 + 5x the account balance after x weeks
The account balance is directly proportional to the number of weeks of deposits if:
A/x = constant
(120 + 5x)/x = 120/x + 5 is not a constant
For example:
After 1 week there will be: 120 + 1*5 = $125 on the account
After 2 week there will be: 120 + 2*5 = $130 on the account
After 3 week there will be: 120 + 3*5 = $135 on the account
But 125/1 <> 130/2 <> 135/3
The account balance is not proportional to the number of weeks of deposits.</span>
It’s 3n-4
I might be right or wrong
