The answer x = -3 is correct ; not really any mistakes made but they do seem to skip a step from 8^(-1) to 2^(-3) if that is confusing you.

8 = 2^(3) 
so
(8)^(-1) = (2^3)^(-1) = 2^(3*-1) = 2^(-3)

Madeline invests $25,000 in an account that offers a compound interest rate of 9.5% per year. Which of the following is the corr
LekaFEV [45]
Use this equation:   Amount after years=Initial investment*(1+Interest rate/time compounded yearly)^number of years*times compounded yearly

So A=25,000(1+.095/1)^8*1
Simplify
A=25000(1.095)^8
Simplify
A=25000(2.07)
Solve
A=$51,671.73

This equation can be used for all problems of this type.

What is 1/2 plus 9/10
Irina18 [472]
Find the common denominator first--> 10
1/2= ?/10    ?=5
so 5/10 +9/10    (Now you just add the numerators and keep the common denominator the same)

14/10 and if you want to simplify it, simply divide both the top and bottom by 2

answer = 7/5
