WebMay 17, 2016 · Find the set of values for $k$ for which the line $y=2x-k$ meets the curve $y=x^2+kx-2$ at two distinct points. I have started my equation like this: Webk ( 1 + k t) − 2 ( 2 + 4 t) + ( 1 − t) = 0. or. ( k 2 − 9) t + ( k − 3) = 0. If k ≠ ± 3, there is a unique solution, namely t = 3 − k k 2 − 9, so the line intersects the plane in 1 point. If k = … horseware leather headcollar

What does y equals kx mean? - Answers

WebAnswer (1 of 2): Set the y values equal to get 2x - 1 = x² + kx + 3 x² + (k - 2)x + 4 = 0. We will get two distinct real solutions if the discriminant is greater than 0. The inequality is (k - 2)² - 4(1)(4) > 0 (k - 2)² > 16 k - 2 > 4 k - 2 > 4 or k - 2 < -4 k > 6 or k < -2 WebFeb 25, 2024 · 1)Tangential distance from line to point (center of circle): 5. d = A x 0 + B y 0 + C A 2 + B 2 where.
