Since d/dx f(y) = (dy/dx)(d/dy f(y)), by differentiating the equation wrt x on both side, 4x^3 + 4y^3(dy/dx) = 0, dy/dx = -(x/y)^3.
At (-1,-3), dy/dx = -1/27
Equation of tangent: y - y1 = m(x - x1) where x1 and y1 are coordinates of a point.
y + 3 = -1/27(x + 1)
Answer:
evaluate parenthesis first:
67/100(consider 67% out of 100) x 119 = 79.73
It is B because when two lines are perpendicular, they are defined as being right angles to each other
