Answer:
2
Step-by-step explanation:
2Y = 10
10 - 6 = 4
x = 2
4/2 = 2
 
        
                    
             
        
        
        
Step-by-step explanation:
sin(x) = M, M > 0
= sin(x - π)
= sin(x)cos(π) - cos(x)sin(π)
= sin(x).(-1) - cos(x).0
= -sin(x) - 0
= -sin(x)
= -M
 
        
             
        
        
        
<span>9c+(8+3c)      
9c+8+3c     (collect like terms)
9c+3c+8
12c+8
12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:
12c+8      (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)
4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)
</span>
