Answer:
"She invested $2500 in 5% account and $5500 in 8% account"
Step-by-step explanation:
Let the amount invested in 5% account be "x"
So, the amount invested in 8% account would be "8000 - x"
Interest amount is the percentage multiplied by amount invested. So
Interest of 5% account = 5% of x = 0.05x
Interest of 8% account = 8 % of 8000 - x = 0.08(8000 - x)
Total interest is the sum of these 2 expressions that EQUATES to 565 (given). Let's solve for x:
and thus,
"8000 - x" = 8000 - 2500 = 5500
Hence,
She invested $2500 in 5% account and $5500 in 8% account

Answer:
We conclude that the function represents exponential growth.
Step-by-step explanation:
Given the function
As the function is of the form
and base 'b' > 1
We know that when the base 'b' of the exponential function > 1, meaning those numbers will get bigger, we call it exponential growth.
As b=8/5 is bigger than 1.
i.e. 8/5 > 1
Thus, we conclude that the function represents exponential growth.
The correct answer is 4x-10
