x = 42/3
-----> 3x=42
F^1(-2) = 2(-2) = -4
f(-4) = 1/2 * -4 = -2
f(f^-1(x)) = x so answer is -2
Answer:
The answer is -5, -4, -3, -2, -1, 0, 1.
Step-by-step explanation:
Because they are behind the number 2
You have the formula. Put in the numbers and solve for r.
The interest earned in 4 years on 5000 is (6500 -5000) = 1500.
.. I = Prt
.. 1500 = 5000*r*4
.. 1500/20000 = r = .075 = 7.5% . . . . . . matches selection B
