Answer:
Step-by-step explanation:
hello :
the point-slope formula is :  
y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope
in this exercice :  x_1 = -1            y_1 = 4             m = 3 
so : y - 4 = 3(x +1)   ...an equation for this line .
  
        
                    
             
        
        
        
Under box 36x + 9, Drag the following:
A.) 9(4x + 1)
D.) (9 . 4x) + (9 . 1)
Under box 9(4x - 1), Drag the following:
B.) (3 . 12x) - (3 . 3)
C.) 36x - 9
Under box (4 . 9x) + (4 . 2), Drag the following:
E.) 4(9x + 2)
F.) 36x + 8
Hope this helps!
        
             
        
        
        
Answer:
Inequalities are different from equations.  If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.
 
        
             
        
        
        
Answer:
x = 3/7
x = 0.43
Step-by-step explanation:
Make x the subject
x > ×7 > + 4 > -4 = 3
3 > + 4 > -4 > ÷ 7 = x
 
        
             
        
        
        
Answer:

Step-by-step explanation:
-The total portion fed to the dog is 7/10 cup
- Canned-3/10
- Dry=7/10-3/10=4/10
-One week has 7 days. we multiply the dry portion per day by the number of days in a week.

Hence, Erin feed her dog 2 4/5 0r 2.8 cups of dry food
