The answer is B.
How?
Take the original equation and multiply the parenthesis by 3:
3x+15-6x=23
Now, unite the two x terms like this
3x-6x+15=23
Now, combine them by doing 3-6 (which is -3), and making that the coefficient on x:
-3x+15=23

Average Price A stock analyst plots the price per share of a certain common stock as a function of time and finds that it can be

mixer [17]

Answer:

42.49 unit price

Step-by-step explanation:

The average price function, S(ave), will be an integral of the price function over the period of time (6 years), that is

S(ave) = $1/6*\int\limits^6_0 {S(t)} \, dt$

= $1/6*\int\limits^6_0 {37+6e^-0.03t} \, dt$

Solving the integral, we have

S(ave) = 1/6*(37t - (6e^-0.03t)/0.03) with the limits being from t = 0 to t = 6

Hence, we have

S(ave) = $37 - \frac{200}{6}*(e^(-0.03*6) - 1)$

This resolves to 42.49 unit price

Please do this with steps

OverLord2011 [107]

Simple...

you have: $\frac{18-2*5}{15+3(-3)}$

To solve this just go slowly..simplify everything out-->>

$\frac{18-2*5}{15+3(-3)} = \frac{18-10}{15+3(-3)}$

$\frac{18-10}{15+3(-3)} = \frac{8}{15+3(-3)}$

$\frac{8}{15+3(-3)} = \frac{8}{15+-9}$

$\frac{8}{15+-9} = \frac{8}{6}$

$\frac{8}{6} = \frac{4}{3}$

Answer is $\frac{4}{3}$ .

Thus, your answer.
