3 and 4 are the correct answer and the picture shows how to solve it :)
You can tell if two lines are parallel, perpendicular, or neither by looking at their slopes and :
- If , i.e. if the two lines have the same slope, the lines are parallel
- If , the lines are perpendicular
- In all other cases, the lines are not parallel nor perpendicular.
Given two points of a line, the slope is defined as the ratio between the y and x variation:
So in this case, we have
Since the two slopes are the same, the two lines are parallel.
4/ (1/2)
=4* (2/1)
= 8
The answer is 8~
Answer:
x > 2
Step-by-step explanation:
First simplify the bracket....to give you...x + 2...then
; 4x + x + 2 > 12....
; 5x + 2 > 12
; 5x > 12 - 2.....then gives you...5x > 10...then divide both sides by 5
then gives you....; x > 2
