SpletSubstitute y = mx+5 into the circle equation. You will get = 10, = 10, = 0. (1) The condition that the straight line is tangent to the circle is equivalent to the fact that the equation (1) has only one root, which, in turn, means that the discriminant of the equation (1) is equal to zero. It gives you an equation for m: d = = 0 SpletAnswer (1 of 2): Let y = mx+ 6 be the tangent to the line y = x^2 -4x+7 at x = a To get the slope, lets take the first derivative of y = x^2 - 4x + 7 at x = a So that dy/da = 2a - 4 . . . . . . . … flash radio tippspiel

SpletFor example, y = x + x is a parabola, also called a quadratic function. Since for point (x 1, y 1) we have y 1 = m x 1 + b, the y-intercept b can be calculated by: b = y 1 - m x 1 How to use this calculator? This rectangular prism calculator will help you to work out the volume, surface area, and diagonal of that solid. y - mx = b. b= .5. SpletQuestion 463056: (a) Find the value of m for which the line y=mx-3 is a tangent to the curve y=x+1/x and find the x-coordinate of the point at which this tangent touches the curve. … Splet27. apr. 2024 · A possible approach: 1) Calculate distance from (0,0) to line y = m x + c.
