Gonzalez Manufacturing borrowed $30000. Part of the money was borrowed at 14%, part at 16%, and part at 18%. The annual interest was $4880, and the total amount borrowed at 14% and 16% was twice the amount borrowed at 18%. Use Gaussian elimination or Gauss-Jordan elimination to find the amount borrowed at each rate.
How much money was borrowed at 14%, 16% and 18%?

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
