Answer:
The cost of extracting the first 50 tons of copper is $151,000.
Step-by-step explanation:
Start-up costs of $150,000.
For the 50 tons of cooper.
So
1 thousand dollars.
$150,000 + $1,000 = $151,000
7x+4.81=49.82x
x=6.43

f(-3) = -4(-3)² + 15 = -4(9) + 15 = -36 + 15 = -21

area of the triangle= 1/2 (6-3)(13-7)
=1/2 (3)(6)
=9
area of rectangle= 6×7
= 42
therefore, area of shape = 42+9
=51
"If you subtract 17 from my number and multiply the difference by negative 4, the result is negative 92.
n= number
(n-17)*(-4) = -92
distribute
-4 *n - 17*(-4) = -92
-4n +68 = -92
subtract 68 from each side
-4n +68-68 = -92 -68
-4n = -160
divide each side by -4
-4n/-4 = -160/-4
n = 40
