Answer:
If they are reflection. I think they are congruent
Step-by-step explanation:
The equation is -3x/y
Plug in the numbers given for x and y
-3(10)/-3.5
-30/-3.5
divide and that's your answer
21x - 19 = 3x + 17 |add 19 to both sides
21x = 3x + 36 |substract 3x from both sides
18x = 36 |divide both sides by 18
x = 2
Just multiply across which is
8*5 = 40
21*16 = 336
40/336 = 5/42
This is correct answer
