Simplified expression is 11y² + 6x - 13
Step-by-step explanation:
- Step 1: Simplify 5y² + 3y - 13 + 6x - 3y + 6y²
5y² + 3y - 13 + 6x - 3y + 6y² = 11y² + 6x - 13
 
        
             
        
        
        
A it is a many to one function
        
             
        
        
        
Sweater = 400
coats = 100
difference= 300
in an equation it would be
4x-x=300
so
3x=300
x=100
sweaters= 4x= 400
coats= x= 100
        
             
        
        
        
Y=x+4
3x+Y=-8
3x+x+4=-8
X=-3. Substitute the value of x
Y=-3+4
Y=1
(X,Y)= (-3,1)
So the answer is C
        
                    
             
        
        
        
In other words, what is <em>y</em> if <em>x</em> is 0.
Look on the graph, a line passes through point, 
So we can conclude that at that very point the input <em>x</em> was 0 and the output <em>y</em> was -3 therefore,

Hope this helps.
