18,020=120(1-(1+0.4233)^-n/0.4233)< br />
i need to figure out what the value -n is

all the calculators i've used say it's not a real number, but i need it to be for a project. can i also get a step by step?

it's due tomorrow

i'll give a brainliest

Start with

Divide both sides by 120:

Simplify the dfraction on the left hand side, and the sum in the parenthesis of the right hand side:

Subtract 1 from both sides:

Change side to both sides:

Simplify the left hand side:

Multiply both sides by 0.4233:

Simplify the left hand side:

Apply the definition of negative exponents:

Invert both sides:

This is why the equation is impossible: the function is an exponential function, and as such, it is always positive. So, there cannot be a value for such that the last equation is satisfied.

astronomers is your final answer! : )

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
