You were not driving for 12 hours.
<em><u>Explanation</u></em>
Distance to the vacation spot is 1500 miles and you estimate that you drove an average speed of 50 mph.
<u>Relationship between distance, speed and time</u> is.......
So, the <u>number of hours you drove</u> 
Given that, including rest stops it’s takes you 42 hours to get to the vacation spot.
Thus, the number of hours you were not driving 
Answer:
D
Step-by-step explanation:
Given that
f(x)=-2x – 1
g(x) = -1/2x+1/2
I The function f( g(x)) = x for all real x.
-2(-1/2X + 1/2) - 1
X - 1 - 1
X - 2
II. The function glAx)) = x for all real x.
- 1/2( -2X - 1 ) + 1/2
X + 1/2 + 1/2
X + 1
III. Functions fand g are inverse functions
Inverse of f(x)
Y = -2x - 1
X = - 2Y - 1
- 2Y = X + 1
Y = - 1/2X - 1/2
Therefore, none of the above answers is correct.
The correct answer is therefore D
Answer:
15 students still haven't given their speeches
Step-by-step explanation:
2/3 of 60 is 40
60 - 40 = 20 left
1/4 of 20 is 5
20 - 5 = 15
15 students still haven't given their speeches
I am assuming theres an addition sign between the 3 and 4.
So basically you want to multiply the 5x by both terms so it will end up being
(5x•3) + (5x•4)
Now simplify:
15x+20x
Hope this helped ^_^
