Combine like terms
-6x² + (-x²) = -6x² - x² = -7x²
-7x² + 15x + 4 is your answer

Answer:
240 melons 
Step-by-step explanation:
First, multiply the # of boxes and # of bags 
(30 * 4 = 120)
Then, multiply that with 2

Answer:
H (x= -3 , y=5)
I (x=8 , y=2)
J (x= -3 , y= -5)
D is the distance between the 2 points so just plug in the x and y cords of each of the corresponding points 
so for (HI)
you plug in 2 on the red x 
and 8 on the red y 
then -3 in the blue x 
and 5 in the blue y
 
        
             
        
        
        
Answer:  D.  8/5 
`
Step-by-step explanation:
This is a proportional relationship which means that  y/x= k .The y value divided by the x value will give you k which is the slope or in other words the constant variable.  
So just divide the y value by the x value to find the k.
(5,8) 
The y value is 8 
The x value is 5 
8/5 = k 
k = 8/5
