The correct answer: D. -4y - 9.
6x+8=-3x-10
9x=-18
x=-2
-3(-2)-10=-4
So x=-2 and y=-4
Simply take the derivative of s(t),
s'(t) = -6
Since the velocity is constant, v(t) = s'(t) = -6 at any given time t.
Answer:
(i)(a - 2y) (3x - 4b)
(iii) (m - n)(m + 4)
Step-by-step explanation:
(i)
3ax - 6xy + 8by - 4ab
= 3x (a - 2y) - 4b (-2y + a)
= 3x (a - 2y) - 4b (a - 2y)
= (a - 2y) (3x - 4b)
(iii)
