Answer:
2/3 x - 2y ≥ 1⇒ y≤ 1/3 x -1/2
(1,6) holds false for the inequality
(2,3) false
(3,2) false
(6,1) holds true for the inequality
The solution (shaded area) lies below the boundary line, which is y = 1/3 x -1/2
Y = kx
72 = k*3
73/3 = k
24 = k
y = 24x
Common ratio = 22/-11 = -2 also -76 / 88 = -2 confirms it.
B/ a0 = -11 / -2 = 5.5 and a1 = 88 / -2 = -44
-3^-3=1/(-3^3)=-1/27 maybe a typo, because you don't have this as an option
could have been -3^-2=1/(-3^2)=1/9
-3^-1=1/(-3^1)=-1/3
-3^0=1
-3^1=-3
-3^2=9
