Answer:
i . 0.10c
Step-by-step explanation:
Just plug a random number, idk what number you'd choose. But my lucky number is 10 so 0.10 x 10 = 1 which is 10% of the original cost XD
yea..hope this helps! :D
 
        
             
        
        
        
Answer: - 235
<u>Step-by-step explanation:</u>
f(x) = -3x² + 13x + 3
f(-7) = -3(-7)² + 13(-7) + 3
       = -3(49) - 91 + 3
       = -147 - 88
       = -235  
 
        
                    
             
        
        
        
The side AB measures option 2.  units long.
 units long.
Step-by-step explanation:
Step 1:
The coordinates of the given triangle ABC are A (4, 5), B (2, 1), and C (4, 1).
The sides of the triangle are AB, BC, and CA. We need to determine the length of AB.
To calculate the distance between two points, we use the formula 
 where ( ) are the coordinates of the first point and (
) are the coordinates of the first point and ( ) are the coordinates of the second point.
) are the coordinates of the second point.
Step 2:
For A (4, 5) and B (2, 1), ( ) = (4, 5) and (
) = (4, 5) and ( ) = (2, 1). Substituting these values in the distance formula, we get
) = (2, 1). Substituting these values in the distance formula, we get

So the side AB measures  units long which is the second option.
 units long which is the second option.
 
        
             
        
        
        
One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3 
and slope m = 

So the equation of line will be 
 And the inequality should be 
Or 
And the other line passes through (-2,3) and (0,2) 
So the y intercept is b=2
and the slope is 
So the equation of line will be 
Or 

So answer is 
 
        
                    
             
        
        
        
Answer:
The median-median line is a better prediction.
Step-by-step explanation:
Both lines predict a value for x=50 that is less than 60. The median-median line value is closer to 60, so could be considered a better prediction.
