Step-by-step explanation:
Answer: Yes this is a right triangle
We can determine this by using the converse of the pythagorean theorem.
a = 5, b = 12, c = 13

Since those a,b,c values work in the pythagorean theorem, this proves we have a right triangle.
X = y - 3
x + 3y = 13
x + 3y = 13 (replace x with y-3)
y - 3 + 3y = 13
4y - 3 = 13
4y = 13 + 3
4y = 16
y = 16/4
y = 4
x = y - 3
x = 4 - 3
x = 1
The answer is A. (1,4)
6x+8 <62
-8 < -8
6x/6 54/6
Answer: x< 9
