Answer:
x = 2
Step-by-step explanation:
note that 4096 = 
, then
=
Since bases on both sides are equal, both 8 , then equate the exponents
2x = 4 ( divide both sides by 2 )
x = 2
Answer: 1/3 (x + 6)
Explanation: given f(x) = 3x - 6.
Let y = f(x) and so y = 3x - 6.
Trade places between x and y.
x = 3y - 6
Solve for y
x + 6 = 3y
y = x + 6/3
Now the new y is the inverse and so y = f-1(x)
f-1(x) = 1/3(x + 6)

2568.75 - 2500 = 68.75;
( ? / 100 ) * 2500 = 68.75 ;
? * 25 = 68.75;
? = 68.75 ÷ 25
? = 2.75;
r = 2.75 %
