The altitude (in feet) of an object in motion, d, after t seconds is given by the equation:
d = –16t2 + vt +h
where v is the initial velocity and h is the initial
height
A catapult launches a stone with an initial velocity of
48 feet per second and an initial height of O feet.
How long will the stone be in flight?
seconds

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
