If acr AC is one fifth of the whole circle, angle AOC is 1/5 of 360,
angle ABC is half of angle AOC, so the m∠ABC=36
So thing of that weird little circle as “of”
Thus: “g of h of x” or g(h(x)). First find h(x) by plugging x in for h and then plug whatever h(x) is in to g.
Ex. If h(x)= 4x + 2 And g(x)= 2x + 5,
g(h(x))= 2(4x + 2) + 5 = 8x + 4 + 5 = 8x + 9

Answer: 
Step-by-step explanation:
Given
A telephone call costs c cents for first 3 minutes and m cents for each additional minute.
Any call beyond 3 minutes costs
where t is the minutes spent beyond 3 minutes
For 6 minutes , t is 3
thus, it can be written
-4x + 9y = 9...............(1)
x - 3y = -6 Multiply through by 3:-
3x - 9y = -18..............(2)
adding equations (1) and (3):-
-x = -9
x = 9
Substitute for x in equation (1)
-4(9) + 9y = 9
-36 + 9y = 9
9y = 45
y = 5
Answer is x = 9 and y = 5
