Answer:

x = -3

Step-by-step explanation:

-4x + 2(5x - 6) = -3x - 39

-<u>4x</u> + <u>10x</u> - 12 = -3x - 39

-4x + 10x = 6x

6x - 12 = -3x - 39

<u>+3x</u><u>      _ </u><u>+3x        </u>

9x - 12 = -39

<u>     </u><u>+ 12</u><u>   </u><u>+12</u>

<u></u>

\frac{9x}{9} = \frac{-27}{9}

x = -3

-30 = -30

Tju [1.3M]

Answer:

f(t) = 500 * (1.035) ^ t

Step-by-step explanation:

A = p(1 + r/n)^nt

Where

A = future value = ?

P = principal = $500

r = interest rate = 3.5% = 0.035

n = number of periods = 1

t = number of years = t

A = p(1 + r/n)^nt

= 500(1 + 0.035/1)^1*t

= 500(1 + 0.035) ^t

= 500( 1.035)^t

= 500 * (1.035)^t

f(t) = 500 * (1.035) ^ t
