Problem Set # (4 points each problem) Use your calculator to help you sketch a graph and find the solutions requested.

  1. 3 x − 4 y + 7 = 0 and 2 x − 5 y =60 Find any points of intersection
    1. y = 3 x^2 − 2 x + 10 and 3 x − 2 y + 5 = 0 Find any points of intersection.
  1. 0 = 5 x^4 − 3 x^2 − x + 7 Use your calculator to find any real roots of this equation.
