Answer:
a = 15
Step-by-step explanation:
The graph of function g(x) is described by g(x)=ax−7, or y = ax−7.
y = g(x)=ax−7 passes through (1/3, -2). We can subst. -2 for y and 1/3 for x to determine the value of the coefficient a:
-2 = g(1/3) = a(1/3) - 7
Solve for a. First, add 7 to both sides: 5 = a(1/3).
Next, multiply both sides by 3: 15 = a, or a = 15.
I'm guessing you are using military time.
Note, 23:00 is the same as 11:00 pm, and 12:20 is the same as 12:20 pm
Also note: 1 hour = 60 minutes
1) Change 1 hour inside 23:00 to minutes
23:00 = 22:60
Subtract
22:60 - 12:20 = 10:40
The time between 12:20 and 23:00 is 10 hours and 40 minutes
