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
I think it would be the first
Answer:
x=2
Step-by-step explanation:
Answer:
y = 2 x = -7
Step-by-step explanation:
2x+5y=-4 2x + 5y = -4 Add both equations
(-x-3y=1)2 -2x - 6y = 2
-y = -2
y = 2
Plug in 2 for y in the equations
-x - 3(2) = 1
-x -6 = 1
-x = 7
x = -7
