Answer:
-1.5m + 4n is the equivalent expression
Step-by-step explanation:
To find the equivalent expression, we combine the like terms.
We are given the following expression:
m + 4n - 2.5m
Combining the like terms:
m - 2.5m + 4n
-1.5m + 4n is the equivalent expression
P=focal legnth is the distance from the focus to the vertex, which also is the disance from the directix to the vertex
therefor
distance from directix to focus=2 times focal legnth
find distance
horizontal distance
from y=-0.6 to y=2.6, that is distance ot 3 units
3/2=1.5
focal distance=1.5
Answer:
You have to see for yourself on the picture we cannot see. But from these statements alone it's either the second or the fourth option.
Step-by-step explanation:
They are perpendicular because their slopes are equal - Doesn't make sense, they would be parallel not perpendicular
They are perpendicular because their slopes are negative reciprocals - Makes sense
They are not perpendicular because their slopes are equal - Makes sense but it does not explain their relationship as well as the statement above
They are not perpendicular because their slopes are not negative reciprocals - Makes sense since that's how perpendicular lines work.
Conclusion, since we can't see the lines. You have to see for yourself on the picture we cannot see. But from these statements alone it's either the second or the fourth option.
If you add a picture I can narrow it down.
5.9, you have to cross multiply to find the answer. Look at khan academy's lesson :)
Answer:
it would be probably the letter M
