What are the vertex, focus, and directrix of the parabola with the equation ? vertex (4, –3); focus (4, –4); directrix y = –2 vertex (–4, 3); focus (–4, –1); directrix y = 7 vertex (4, –3); focus (4, –7); directrix y = 1 vertex (–4, 3); focus (–4, 2); directrix y = 4

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

y=x+9

?

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

answer: it depends on what the tax percentage
