Answer:
Undefined 
Step-by-step explanation:
The square root of a negative number does not exist in the set of real numbers so it would be Undefined
 
        
             
        
        
        
Answer:
Whether you're teaching the meaning of fractions or fraction operations, visual models can help students connect fractions to what they already know. Division is an essential foundation for fractions. Once students can divide objects into equal groups, they can begin to grasp dividing a whole into equal parts.

Answer: (x, y) = (-x, -y)
Step-by-step explanation:
To solve this, you can match the coordinates of points on the triangles and choose the correct answer from there. 
The highest point on the triangle, S, has coordinates of (3, 5). 
The reflected triangle's point S has coordinates of (-3, -5). 
Point Q on the triangle has coordinates of (1, 0)
Point Q on the reflected triangle has coordinates of (-1, 0). 
Matching these two points and their reflections to the answers, the only answer that fulfills both points correctly is (x, y) = (-x, -y).
