0.9 x 1.1= please help so confused!!

Find the balance at the end of 4 years if 1000 is deposited at the rate of

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142

Yvaries inversely as x. y =12 when x=5. find y when x=4
