Answer:
The lines are perpendicular
Step-by-step explanation:
we have
isolate the variable y
----> equation A
The slope of the line A is 
-----> equation B
The slope of the line B is 
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In this problem
The slopes of line A and line B are opposite reciprocal
therefore
The lines are perpendicular
Answer:
=1050 wildebeests
Step-by-step explanation:
We can form an arithmetic series for the wildebeest migration.
Sₙ=n/2(2a+(n-1)d) where n is the number of terms, d is the common difference and a is the first term.
a=24
n=20
d=3
Sₙ=(20/2)(2(24)+(20-1)3)
Sₙ=10(48+57)
=1050 wildebeests
A hexagon will rotate onto its self at 120 degrees.
Answer:
7/64
Step-by-step explanation:
7/6÷8=7/6*1/8=7/64
Hope this helps :)
2=2
63= 3* 3* 7
14= 2*7
LCM (2,63,14)= 2*3*3*7= 126
The least common multiple (LCM) of 2, 63, and 14 is 126~
