Can someone answer it, and plot it, for 20 points and brainliest answer? p.s. they're the same ! : )

Which number line represents the solution set for the inequality -1/2x> 24?

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
