Use Pythagorean thrm
17^2+10^2=21^2
289+100=441
389≠441
This is not a right triangle
The Correct option is -4
because every other terms result in value = 4, where's -4 is the only different one hence doesn't belongs yo other three

Step-by-step explanation:
Answer:
x = 2, y = 9 or (2,9)
Step-by-step explanation:
Hello!
The first equation "y = 5x - 1" is telling us that y is equal to 5x - 1
We can plug in the first equation into the second like this:
2x + y = 13 (we know y so we can plug it in)
2x + (5x - 1) = 13
2x + 5x - 1 = 13
7x - 1 = 13
Now we add 1 to both sides
7x - 1 + 1 = 13 + 1
7x = 14
x = 2
Now we plug in x to find y:
y = 5x - 1
y = 5(2) - 1
y = 10 - 1
y = 9
