y = a sin b(x±h) ± k
a : amplitude => take absolute value
b : angular frequency
h : horizontal shift ( phase shift). (+ left, - right)
k : mid. line or vertical shift ( + up, - down)
period: the length of one cycle
period = 2π/b ( for sines, cosines. if tangent : p = π/b)
Answer:
w = 18
Step-by-step explanation:
Given
(w + 18) = 12 ← distribute parenthesis on left side
w + 6 = 12 ( subtract 6 from both sides )
w = 6 ( multiply both sides by 3 to clear the fraction )
w = 18
