Answer:
3r+5
Step-by-step explanation:
Since -5r and 8r both have r in them, we can combine them and the expression looks like:
3r+5
Which is our answer.
Answer:
d. 4c + 11d + 15
Step-by-step explanation:
This is a pretty simple combining like terms problem.
10c - 6c = 4c
3 + 12 = 15
7d + 4d = 11d
Therefore, our expression will be 4c + 11d + 15.
So, they are saying that all those segments are equal.
If segment LM is 5, that means that all the other lines are also 5 because they are all equal.
So,
ML + KL + KJ = JM
5 + 5 + 5 = JM
15 = JM
Hope this helps!
Answer:
y -5 = -4(x -(-1))
Step-by-step explanation:
because a perpendicular line is the negative reciprocal of the slope. the slope was 1/4, the negative reciprocal of the is -4. then plug into the equation
y-y1 = m (x-x1)
