You plug in f(x) into where x is within g(x) so you get G(f(x))=(X+6)^4
Answer:
x = 6
Step-by-step explanation:
- <em><u>Pull out like factors:
</u></em>
-4x - 13 = -1 • (4x + 13)
- <em><u>Equation at the end of step 2:
</u></em>
-178 - (-5x + -4 • [4x + 13] ) = 0
- <em><u>Pull out like factors:
</u></em>
21x - 126 = 21 • (x - 6)
- <em><u>Equation at the end of step 4:
</u></em>
21 • (x - 6) = 0
x-6 = 0
- <em><u>Add 6 to both sides of the equation:</u></em>
x = 6

Answer:
- <em><u>The reduction is 8.6%</u></em>
Explanation:
Call F the full monthly pension of a person retiring at 62.
If a person continues to work the pension grows at a rate of 6% per year, compounded monthly, so use the compounded growing formula:
Where r = 6 / 100 = 0.06, and t = number of years after retirement.
<u>For retirement at 65.5</u>:
<u>For retirement at 67</u>:
<u>Percent reduction of people who retire at 65.5 compared to what they would receive at 67</u>:
