Jacob gives Patrick a number. Patrick multiplies the number by 3, then subtracts 12 and gives Jacob that number. Jacob multiplies the number by 3, then subtracts 12 and gives that number to Patrick. This repeats several times. If the sum of Patricks first three numbers is 15 852, what was Jacob's original number?

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x′y′z′, with vertices x′(4, -2), y′(4, -3), and z′(1, -4). the type of transformation that triangle xyz undergoes is a . triangle x′y′z′ then undergoes a transformation to form triangle x′y′z′, with vertices x″(4, 2), y″(4, 3), and z″(1, 4). the type of transformation that triangle x′y′z′ undergoes is a .
