Which equations can be used to find the value of x? 4x - 90 = 180 2x + 90 = 180 4x + 90 = 180 2xº 2x + 2x + 90 = 180 2xº 2x + 90 = 360 4x = 90 Two equations are shown. y = 3x y = x - 3 Which statements about the relationships between x and y are TRUE? Select all the correct answers. In y = 3x, the value of y is 3 times the value of x. In y = 3x, the value of y is 3 greater than the value of x. In y = 3x, the value of x is 3 less than the value of y. In y = x - 3, the value of y is 3 times the value of x. In y = x - 3, the value of x is 3 greater than the value of y. In y = x - 3, the value of x is 3 less than the value of y. Match each term to the correct description. Operation that maps a geometric figure onto a new figure Transformation ?
