substitute the given values of the variables into the equation. write true or false to indicate whether the
values make the open sentence true or false. values: x = 9, y = 0.4, z = 2x + = 2-4

41/17 as a decimal rounded to the nearest hundredth

50 plz, given the system of equations, match the following items. x + 3 y = 5 x - 3 y = -1 a) x-determinant b) y-determinant c) system determinant match the following to the pictures below.
