Suppose you want to determine the number of miles you can drive in your car. your car gets 28 miles per gallon. the number of miles traveled varies directly with the number of gallons of gas the tank holds. write the direct variation equation that represents this situation. let y be the dependent variable and let x be the independent variable.

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 .
