-9x + 3y = 18
x - 3y = 6

Pls i’m dumb as heck i’ll give y’all so many points if that encourages you

Write a recursive sequence that represents the sequence defined by the following explicit formula:

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39
