The value of the bike after a year becomes only 80% of the value a year ago. In this given, the initial amount $500 should be multiplied by 80% 5 times. The answer would be $163.84. Thus, after 5 years the dirt bike would only be $163.84.
The -2 has a multiplicity of 2
Since the order of (x+2) is squared, i.e. power is 2
-a) function 2, function 4
-b) function 4
-c) function 2
If you find a common denominator for the two, which is 12 it will make it easier to add. So 4 3/12 + 3 4/12 = 7 7/12.
your answer is 7 7/12.
