Answer:
2
Step-by-step explanation:
what you do is -4(2)^-2 which is -1
then you do 3(5)^0 which is 3 
then you add it together and it is 2
 
        
             
        
        
        
A coefficient of r = -1 is a negative so the dots would move downward as they move to the right ( higher dots are on the left side, lower dots on the right side. As the coefficient gets closer to -1 the dots form more of a straight line then being scattered across the graph.
The last graph, which is marked with the blue dot is the correct one.
 
        
                    
             
        
        
        
Answer:
51.84 cm
Step-by-step explanation:
Solution,
We have,
Area of the square= L²
According to question,
168 cm²= L²
√168 cm²= L²
√(12.96 cm)² = L
12.96 cm= L
Now,
We got,
Length of the square= 12.96 cm
By using the formula of perimeter of square,
We have,
Perimeter of square= 4L
                                  =4×12.96 cm
                                  =51.84 cm
Hence, the perimeter of square is 51.84 cm.
 
        
                    
             
        
        
        
Answer:
<h2>        
 X-intercept: (2, 0)
</h2><h2>
         Y-intercept: (0, 6)
</h2>
Step-by-step explanation:
X-intercept means y-coordinate of 0:
6x +2×0 = 12
 6x = 12
   x = 2         ← x-coordinate
Y-intercept means x-coordinate of 0:
6×0 + 2y = 12
 2y = 12
   y = 6         ← y-coordinate
