Answer:
6x - 6
Step-by-step explanation:
<em>The only step necessary here is to simplify. We can subtract 18 from 12 since they are like terms. </em>
6x - 6.
<em>That's it! That's your final answer. </em>
identity used is
x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).
then use
(x+y+z)² = x²+y²+z²+2(xy+yz+xz)
225= 83 + 2(xy+yz+xz)
xy+yz+xz = (225-83)/2
xy+yz+xz= 142/2
xy+yz+xz= 71
ok
now use identity
x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).
now
x³ + y³+ z³– 3xyz = 15 (83 – xy – yz – zx).
= 15[83 - (71)]
= 15×12

The inverse function is f(x) =
, which makes the inverse at x = 2 equal to 0.
All inverse functions can be found by switching the x and f(x) values. Once that is done, solve for the new f(x) value. The result will be the inverse of the original function. The step-by-step process is below.
f(x) = 3(x + 2) - 4 ----> Switch the x and f(x)
x = 3(f(x) + 2) - 4 ----> Add 4 to both sides
x + 4 = 3(f(x) + 2) ----> Divide both sides by 3
= f(x) + 2 ----> Subtract 2 from both sides.
f(x) = 
The end is your inverse function. So then we can evaluate when x = 2.
f(x) = 
f(2) = 
f(2) = 
f(2) = 
f(2) = 0
Answer:
900
Step-by-step explanation:
First you need to find the amount of colored copies were made. Then after you multiply by the amount of colored copies made by 9 (9 x 100)
