3y-5x=9
y=-5/3-12
determine whether each pair is parallel perpendicular neither

Neither

Step-by-step explanation:

I assume you left and x out for the first line: so y= -(5/3)x - 12

and y = (5/3)x + 3

Comparing the two, they are neither parallel nor perpendicular.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
