Answer:
D
Step-by-step explanation
Since we are reflecting across the x axis, all of the y coordinates will remain the same. You find the distance away from the x = 4, double it, and add that value to x. So,
X' is now (8,3)
Y' is now (6,0)
Z' is now (4,2) because its x was 0, and anything * 0 = 0 so it does not move.
B would be 11 (if thats what youre asking)
Hope this helps!

Step-by-step explanation:
Given




Required
Number of questions answered
First, we need to get the total correct marks obtained by Roy
This is calculated by multiplying the correct marks by number of correct answers


Subtract this from the total scores obtained; This gives the total incorrect answer obtained by Roy


Open bracket


Divide this by -2 to get the number of incorrect answers


Add this to the number of correct answers to give the total number of question answered



<em>Hence, Roy answered a total of 20 questions</em>
