During a period of extreme cold the average daily temperature dropped decreased by 1.5 degree Feach day. How many days did take for the temperature to decrease by 9 degree F? Which equation would you use to find the solution?
1) x+1.5=9
2) x-1.5 = -9
3) -1.5x=-9
4) 1.5x= 9

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 .
