m = , (x₁ , y₁) = (-2, -4)
y - y₁ = m(x - x₁)
y -(-4) = (x - (-2))
y + 4 = (x +2)
y + 4 = + 1
y = - 3

we are given an algebraic function in x, such that
To find when second derivative >0
For this let us find first and second derivative by successive differentiation.
when ii derivative >0 we have
60x^3-30>0

Answer:
The relationship of the angles is complementary.
Answer:
78
Step-by-step explanation:
angle ACD + angle DCB = 180 (Angles on straight line)
4x + 2 + 3x + 3 = 180
7x + 5 = 180
7x = 180-5
7x = 175
x = 175 / 7
x = 25
angle DCB = 3x +3 = 3*25 + 3 = 75 +3 = 78
