Given:
The vertices of a triangle are R(3, 7), S(-5, -2), and T(3, -5).
To find:
The vertices of the triangle after a reflection over x = -3 and plot the triangle and its image on the graph.
Solution:
If a figure reflected across the line x=a, then



The triangle after a reflection over x = -3. So, the rule of reflection is


The vertices of triangle after reflection are


Similarly,



And,


Therefore, the vertices of triangle after reflection over x=-3 are R'(-9,7), S'(-1,-2) and T'(-3,-5).
Answer:
Step-by-step explanation:


-2/3
first do y2-y1 over x1-x2
then it’ll be 2-4 over 5-2
coming out as -2/3
Answer: 247
Use long multiplication to evaluate.
After that divide your answer by either 13 or 19 and see if you get one of those answers.
247÷19=13
247÷13=19
