Which expression is equivalent to StartFraction negative 9 x Superscript negative 1 Baseline y Superscript negative 9 Baseline Over negative 15 x Superscript 5 Baseline y Superscript negative 3 Baseline EndFraction? Assume x not-equals 0, y not-equals 0.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

-5/3

step-by-step explanation:

when a line is perpendicular to another line, it's slope is the negative reciprocal of the original line. the slope of the line given is 3/5 so the slope of the line perpendicular to this one is -5/3 : )
