Answer:
The expression would be 5x + 2y = 20
Step-by-step explanation:
We let x be no of hardcover books, and 5x the cost of those books
Same for paperbacks.
then we add them up to 20.
Done!
F(5) = - 2f(4) + 1
f(4) = -2f(3) + 1
f(3) = -2f(2) + 1
f(2) = -2f(1) + 1
Therefore:
f(2) = -2(3) + 1 = -5
f(3) = -2(-5) + 1 = 11
f(4) = -2(11) + 1 = -21
Therefore f(5) = -2(-21) + 1 = 43
