Help fast please Line k is perpendicular to the line y=(2/3)x−4 and passes through the point (5,−7). Which is the equation of line k?
A:y+7=(2/3)(x−5)
B:y−7=(2/3)(x+5)
C:y−7=(−3/2)(x+5)
D:y+7=(−3/2)(x−5)

Which fraction below is equivalent to 10/12?

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
