The answer is 16. Because 2x2=4, 4x2=8, 8x2=16. And you write it like a 2 and a small 4 in the top right hand corner of the 2.
Rewrite the equation as
If we choose , the right hand side becomes zero, and so does the left hand side.
If you graph the two functions and , you'll see that there are only two solutions, so the ones we found are the only ones.
Answer:
Slope = 15.2970585
Step-by-step explanation:
Answer:
average speed = distance / time
60 = distance / (13.20 - 10.40)
13.20 - 10.40 = 2 hours 40 minutes = 2 2/3 hours
60 = distance / 8/3 = 3 d / 8 (where d = distance)
3d = 480
d = 480/3 = 160 miles
