ANSWER

EXPLANATION
The boundary line passes through (-2,2) and (0,-2).
The slope of this line is


The y-intercept is , c=-2.
The slope-intercept form of this line is given by;

We substitute values to obtain;

Since the lower half-plane is shaded the required inequality is 

 
        
             
        
        
        
Answer:
 k = 4/5
Step-by-step explanation:
First, rewrite 5/6k as (5/6)k; this is "five sixths of the variable k."
Next, identify the LCD.  It is 6.  Then the given equation becomes
5k + 4 = 8
Consolidate the constant terms:  
5k = 4
Solve for k:  k = 4/5
 
        
             
        
        
        
Answer:
3
Step-by-step explanation:
2x + 3 = -x + 12
subtract 3 from both sides 
2x = - x + 9 
add x to both sides 
3x = 9 
divide by 3 
x = 3 
 
        
             
        
        
        
Answer:

Step-by-step explanation:
To find the equation of this circle, we must know the center and the radius.
We can find the radius by dividing the value of the distance formula by 2 (since  ):
):

We can then find the center of the circle by averaging the coordinates:


Then, we substitute these values into the equation of a circle:

 
        
             
        
        
        
15 inches long add 7+5 to get the full total of miles
