Use row reduction to solve the system of equations. x-2y+z = 4
3x - 5y- 172 = 3
2x - hy + 432 = -5

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

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 .
