Answer:
$22.50
Step-by-step explanation:
C= 0.20X+14.50
C=0.20(40)+14.50
C=8+14.50
C=22.50
 
        
                    
             
        
        
        
Area of the triangle = 1/2 * base * <span>height 
base = 16 in
</span>height  = 16 in
Area = 1/2 * 16 * 16 = 128 in.

Answer: (0,-15)
--------------------------------------------------
Explanation:
Add up the x coordinates to get 1+(-1) = 0. Divide this sum in half to get 0/2 = 0. Therefore the x coordinate of the midpoint is 0.
Repeat for the y coordinates. First add the y coordinates to get -7+(-23) = -30. Then divide that result in half to get -30/2 = -15. So the y coordinate of the midpoint is -15.
Overall, the midpoint is (0,-15).
        
             
        
        
        
Answer:
2) Vertical translation of 10 units
Step-by-step explanation:
Given
H and H'
Required
Which maps H to H'
First, we pick the coordinate of any point on H

First, we pick a corresponding coordinate on H'

The above coordinates show that H and H' are not a reflection of one another because neither of the x or y coordinates negate one another.
By looking at the coordinates of H and H, we have:
H:  and H':
 and H': ---  The same x coordinates
 ---  The same x coordinates
H:  and H':
 and H':  --- Different y coordinates
 --- Different y coordinates
The difference between the y coordinates is:





Hence,
<em>2) Vertical translation of 10 units
</em> is correct.
