Answer:
2/3
Step-by-step explanation:
The numbers greater then 2 are 3, 4, 5, 6
That's four numbers that are greater then two.
or 4/6, then you just reduce it by dividing by two on the top and bottom
4/2 =2
6/2 = 3 so the answer is 2/3
Answer:
8*5^n-1 / 2^n-1 = n
This is the function for your sequence
Answer:
perpendicular
Step-by-step explanation:
start but putting each line into the standard line format
2x-y=-5
-y=-2x-5
y=2x+5
x+2y=-6
2y=-x-6
y=-(1/2)x-3
if lines are parallel the slopes would be the same. 2 is not equal to -1/2
if lines are perpendicular the slope of one would be the opposite inverse of the other.
negative inverse of 2 = - (1/2)
so the lines are perpendicular
