If 5x2 + y4 = -9 then evaluate the second derivative of y with respect to x when x = 2 and y = 1. Round your answer to two decimal places. Use the hyphen symbol, -, for negative values. (4 points)

Solve for x -2.3(r - 1.2 ) = -9.66 enter you answer as decimal.

The center of a circle represent by the equation (x+9)^2+(y-6)^2=10^2 (-9,6), (-6,9), (6,-9) ,(9,-6)
