Answer:
No, it is a parabola. (assuming that you meant to write 6x² - 2y = 7).
Step-by-step explanation:
If there is a square in the x or y, this gives it away that it cannot be a straight line.
 
        
             
        
        
        
Answer: 14
Step-by-step explanation: 
Okay so it asks in all, which means morning distance + afternoon distance
We got the afternoon distance so now we have to find the morning one
it says the afternoon distance (6), is 25% less than the morning distance.
Which means the afternoon distance is 0.75 of the morning distance.
so 0.75x = 6, x = 6/0.75 = 8
Then you add 8 to 6 to get 14

Answer:
(−∞,+∞)
Step-by-step explanation:
The cotangent function can take up any values depending on the value of 
x
 , the independent variable.
And thus, the range 
(
−
∞
,
+
∞
)
 is justified.
The domain is all real numbers other than integral multiples of 
π
 where, the function is not defined.
