Answer:
1750 m/s
Step-by-step explanation:
1km = 1000m
1 hour = 60 minutes = 3600 seconds
( 630 * 1000 )/ (60 * 60)
= 1750 m/s
-60 -90 -120 it’s going by -30 and that should figure out the next three te rms
It it is the first choice i mentioned then B is the answer.
Answer:
x = -1/9
Step-by-step explanation:
first let's think of x as 1x so than x^2 is basically 1x.
you bring down 8x + 1 = 0 so you have x + 8x + 1 = 0.
than you add x and 8x which equals 9x.
you bring the problem down one more time so 9x + 1 = 0.
you subtract 1 from each side so the 0 becomes because 0 - 1 is -1.
So than you bring the rest of the problem down 9x = -1
Last thing you do is divide 9 from both sides which x = -1/9.
