Y = -2/3x + 2
y = 3/2x + 9
These lines are...

Perpendicular

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes

-2/3 negated is

2/3

The reciprocal (flip the numerator and denominator) of 2/3 is

3/2

So, the lines are perpendicular

Hope this helps! :)

answer: what do you mean

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
