Answer:
A meteor shower is a celestial event in which a number of meteors are observed to radiate from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories.
Ummm this has to be in your textbook
Answer:
1.25a+4.4
Step-by-step explanation:
First add the variables (in this case the only variable is a) so it would be 1.5a+0.25-0.5a = 1.25a.
Then add the non variable numbers together which would be 4.7-0.3 = 4.4.
Any of the following answers are correct:
-The function moves down to -6 on the y axis
-The function moves down 9 points from its original position on the y axis
-The function performs a vertical shift, down to -6 on the y axis
They are perpendicular. If you normalize both functions into y=ax + b form, you get:
-x-3y=-18 => -3y = -18+x => y= 6 - 1/3 x
9x-3y=-27 -> -3y = -27-9x => y= 9 + 3 x
Just comparing the slopes, you see they are -1/3 and 3, which are each other's negative reciprokes. Negative reciprocal slopes are perpendicular.
