- Using the language of research methodology, Dr. Comeaux's sample is both a Representative and Random sample.
A ray is a line has one endpoint and a line that goes on forever.
Answer:
Step-by-step explanation:
Substitute 4x for Y: 4x = -2x -6
Now add 2x to both sides
(due to reciprocal, the opposite of -2x is positive 2x): 4x + 2x = -2x +2x -6
Add common like terms
(4x + 2x = 6x and -2x + 2x cancel out leaving -6 alone): 6x = 6
Now get X alone by dividing the 6 to both sides: 6x/6 = -6/6
Since you're dividing a negative and a positive, the outcome will be a negative so the answer is: X= -6
Hope this helps :)
