Answer:
f(2) = 0
Step-by-step explanation:
Plug x = 2 into the formula for f(x):-
f(2) = 2(2) - 4
= 4 - 4
= 0
If A = 0, then Ax + By = C would be 0x + By = C.
The graph will be a horizontal line.
Answer:
11 dimes and 4 nickles
Step-by-step explanation:

Hence the fraction of a pie that each slice represent is: 1,8
