The answer is f(2y) = 8y^2 - 8
In order to find this, we need to put 2y in where x was in the original equation. From there, we follow the order of operations to simplify.
f(x) = 2x^2 - 8
f(2y) = 2(2y)^2 - 8
f(2y) = 2(4y^2) - 8
f(2y) = 8y^2 - 8
Answer:
The total change in his account is of -$85, that is, a loss of $85
Step-by-step explanation:
We combine these changes. So
On Tuesday, he withdrew $90 from his account, which means that, the total change, initially of $0, is now of -$90.
On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70
On Friday, he wrote a check of $15, removing 15 from his account, which means the total change will be of -$70 -$15 = -$85
2580/3 * 100 = 860 * 100 = 86,000
Check:
86,000 * 0.03(3%) = 2580
The selling price of the house is $86,000.
