Answer:
m=3 is the slope
Step-by-step explanation:
<h2>The value of StartFraction 6 Over x EndFraction + 2x2, when x = 3 is 20.</h2>
Explanation:
The given expression is 
When x = 3, the expression becomes 

= 2 + 18 = 20
Search up heating curve chemistry: it should look somewhat like that lol :). But, the last interval should have a small slope, the middle interval a big slope, and the first interval: a medium slope.
Answer:
2.5 hours
Step-by-step explanation:
The product of speed and time is distance. If the distance is the same, then time is inversely proportional to speed. At 60/50 = 6/5 times the speed, the return trip will take 5/6 times the time:
(5/6)(3 hours) = 2.5 hours . . . time for return trip
