diana is right i got a 100

No, it is D because if we have C(3,-1) and we move 4 units to the left, that is subtracting 4 from the x-coordinate (which is 3-4= -1). And if we move 1 unit up, that is adding 1 to the y-coordinate (which is -1+1= 0)

A. x = 2√[ y^2 + (2.5)^2 ] cm (using Pythagorus theorem) B. x^2 = 4y^2 + 25 => 2x dx/dt = 8y dy/dt => dx/dt = 4 (y/x) dy/dt When x = 12 cm, y = (1/2)√[ 144 - 25 ] = 2.727 cm => dx/dt = 4 (2.727/12) x 3 cm/s = 2.727 cm/s.
