Answer:
For a, the machine depreciates 20% of its current value each year. So, It will lose 20% of its value in the first year. Then in the second year, it will lose 20% of THAT value (not of the original value) and so on.
b) Since the machine loses 20% of its value each year, it retains 80% of its value each
Answer:
Below in bold.
Step-by-step explanation:
f(n) = |-2n| - 6
The vertical lines about the -2n mean the 'absolute value' of the expression So if -2n is negative the absolute value is positive.
n = 19 , f(n) = |-2*19| - 6 = |-38| - 6
= 38 - 6 = 32.
In the same way:
n = 20, f(n) |-40| - 6 = 40 - 6
= 34.
n = 21, f(n) = 36
n = 22, f(n) = 38.

Answer:
-4
Step-by-step explanation:
-129 = 6(7 + 7x) - 3
Distribute the 6 into the parentheses.
-129 = 42 + 42x - 3
Add like terms.
-129 = 39 +42x
Subtract 39 from both sides.
-168 = 42x
Divide 42 from both sides.
-4 = x
