Gaby decorates her room with red and white colored lights. she bought x red lights at $0.65 each and 12 white lights at $1.42 each. The average cost of the lights in the room is $0.95. choose on equation to model the situation. A) 12 + 0.65x =9.5x
B) 0.65x + 3 = 0.95(x + 12)
C) 0.65x + 1.42 = 0.95x
D) 0.65x + 17.04 = 0.95(x + 12)

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
