(15,-25)(-12,11)
slope = (11 - (-25) / (-12 - 15) = - 36 / 27 which reduces to - 4/3
y = mx + b
slope(m) = -4/3
use either of ur points (15,-25)...x = 15 and y = -25
now we sub and find b, the y int
-25 = -4/3(15) + b
-25 = - 20 + b
-25 + 20 = b
-5 = b
so ur equation is : y = -4/3x - 5 <==
Think of it as 12/95. 12.63
C’(500)=80 means at 500 pounds of documents, the cost is increasing at a rate of $80 dollars/pound
Answer:
$1,577.74
Step-by-step explanation:
You are going to want to use the continuous compound interest formula, which is shown below.

<em>A = total
</em>
<em>P = principal amount
</em>
<em>r = interest rate (decimal)
</em>
<em>t = time (years)
</em>
<em />
First change 3% to its decimal form:
3% ->
-> 0.03
Next, we can plug in the values into the equation:


The last step is to subtract 8,000 from 9,577.74:

The total interest earned is $1,577.74
