Answer:
-18
Step-by-step explanation:
-15+6=-9
the absolute value of -9 is 9
and 9*-2=-18
 
        
                    
             
        
        
        
Answer:   D.  y = -4x + 4 
Step-by-step explanation:
Notice that the y-intercept is when x is zero and the x intercept is when y is 0. 
and to write in the equation in slope intercept form , you will need the slope and the intercept. 
We will use the y and x intercepts to find the slope, by find the difference in their y coordinates and dividing it by the difference in their x coordinates.
y intercept: ( 0,4)  
x intercept: (1,0) 
y coordinates difference:  4 - 0 = 4 
x coordinates difference:  0 - 1 = - 1  
Slope:  4/-1 =  -4  
Since the slope is -4 and the the y intercept is 4 , the equation will be 
  y = -4x + 4

If Ali has x cards, then Belinda has 2x cards. 
If Ali has x cards, then Charlie has x+5 cards. 
2x (Belinda) + x+5 (Charlie) + x (Ali) = 33 (total)
2x + x+5 + x = 33
Now simplify the equation... x+x+5 can be simplified as 2x+5. 
2x+5 plus 2x can become 4x+5. 
So their total number is 4x+5. 
So 4x+5=33. 
You want to isolate the variables and numbers. 
To remove the 5 from the left side, subtract 5 from both sides. 
4x+5-5=4x - 33-5=28
So the equation now is 4x=28
To remove the 4, divide each side by 4. 
4x÷4=x - 28÷4=7
So x equals 7, Ali has 7 cards.
