It would be 45. He has 300, and the interest rate is 5%. 5% of 300 is 15. and he earns that 5% once per annum (which is once per year) so 15 dollars of interest a year for 3 years is 45 earned in interest.
Yes!
-5 - 2 = -7;
-12 - (-5) = -7;
-19 -(-12) = -7;
-26 -(-19) = -7.
Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x2−1 f - 1 ( x ) = x 2 - 1 is the inverse of f(x)=2x+2 f ( x ) = 2 x + 2 .
