4. ### Find the value of k if the straight line 2x-3y=k is a tangent to the circle of radius 5 and center (3, -1).?

If 2x - 3y = k, then 2x = k + 3y, so x = 0.5k + 1.5y The circle is: (x - 3...0.25k^2 - 3k - 15) If the line is tangent to the circle, then k is real and there is only one possible solution for y, so the...
