Answer: C. 2
Step-by-step explanation:
(5,-8) after a 180 degree counterclockwise rotation about the origin is (-5,8)
Answer:
4.875
Step-by-step explanation:
LM = 16,
MN = 13x
LN = 19x + 10
Now look at the alphabets and imagine the line in your head. just take it as a straight line
L M N
|---------------|------------------|
Like this, so we can see that LM+MN = LN
Therefore
LM +MN = LN
16 + 3x = 19x + 10
3x - 19x = - 16 +10
-16x = - 6
16x = 6
8x = 3
x = 3/8
Now put this value of x into MN
MN =13x
= 13 (3/8)
=4.875
