Answer:

x = 0

Step-by-step explanation:

First, multiply the -3 by two (<u>-3</u>(x + 2)<u>2</u> + 4 = -8) -- -6(x+2)+4 = -8.

Then, subtract 4 from both sides (-6(x+2)+<u>4</u> = -8) -- -6(x+2) = -12

After that, divide both sides by -6 (<u>-6</u>(x+2) = -8) -- \frac{-6\left(x+2\right)}{-6}=\frac{-12}{-6}

Simplify -- x+2=2

Subtract 2 from both sides (x+<u>2</u>=2) -- x = 0

Hope this helped! Good luck with future math problems :)

Kaylee deposited $1,450 in an account that earns 2.596 interest compounded annually. Which function represents the situation, wh
e-lub [12.9K]

Answer:

f(t) = 1450(1.025)^{t}

Step-by-step explanation:

Given

P =1450 -- principal

r = 2.5\% --- rate

n = 1 --- compounded once a year

Required

Determine the function for compound interest

Compound interest f(t) is calculated as:

f(t) =P(1 + r/n)^{nt

So, we have:

f(t) = 1450(1 + 2.5\%/1)^{1 * t}

f(t) = 1450(1 + 2.5\%)^{t}

f(t) = 1450(1 + 0.025)^{t}

f(t) = 1450(1.025)^{t}
