Answer:

Step-by-step explanation:
a reciprocal is a number that when multiplied by a given number gives 1 as product.
16 * x = 1
x = 1/16
9/10 * x = 1
x = 10/9
it is a linear equation
if you take the negative of x and subtract 1 you get Y
so the answer is A
I'm pretty sure it depends what kind of triangle it is
