for example b is not a function because we have (0,-7) and (0,-9)
I believe the answer is 26, i hope this helps!
Answer:
C
Step-by-step explanation:
Since the company earns $0.05 for every mile, we would multiply m by 0.05. We also add it with 30 since it is a base charge. This makes it C
It can't be A or B since that would mean the company earns $30.05 for every mile.
It can't be D since that would mean the company earns $30 for every mile with a base charge of $0.05.
Use inverse operations and subtract 3 from 9 which is -12 then divide -12 by 6 which is -2
-9=3+6x
-3 -3
-12=6x
-12/6=6x/6
-2=x
