Answer:
x= - 50/9
Step-by-step explanation:
multipy both equations by 12
9x+60=10
then move the constant to the right hand side and change it's sign
9x= 10 - 60 
calculate difference 
9x = -50
divide both sides by 9
x= - 50/9
 
        
                    
             
        
        
        
Imagine the unit circle. The cot(theta) is a line from (0,1) to (-4,1). Imagine it is part of a triangle with the origin (draw it!).
Then the hypotenuse length is √(1+4²) = √17.
The sine rule says that sin(90)/√17 must equal sin(theta)/4, and sin(90)=1, so 
 
 
        
        
        
Answer:
- 1.375
Step-by-step explanation:
Each dot is worth -1/8 of a unit when moving left. 
So the coordinates of the dark dot are - 1 and - 3/8 
or - 1.375 . The word coordinates (plural) bothers me. It all depends on how you have been asked to represent these points. Another possibility is (-1.375,0). You have to choose from the examples you have been given. I wouldn't do that because you have not been given and xy graph.
