Answer:
y = x^2 - 4
Step-by-step explanation:
The vertex of a parabola is exactly halfway between the focus and the directrix. If the focus is at (0, -6) and the directrix is the line y = -2, then we do this to locate the vertex: Draw a vertical line through (0, -6) also crossing the line y = -2. The y value halfway between y = -6 and y = -2 is y = -4, and the vertex is thus (0, -4).
Using the vertex method, write out the equation of this parabola, starting with the general form y - k = (x-h)^2, where (h, k) is the vertex. Here h = 0 and k = -4
We get: y + 4 = (x - 0)^2, or y + 4 = x^2, or y = x^2 - 4. As a check, let x = 0; y = -4, which is the y-coordinate of the vertex.
Answer: The factory produced 46845.3076923 cookies, though in context the answer does not make sense. If you were to estimate then it'll be 46845 cookies.
Answer:
Yes
Step-by-step explanation:
115 ÷ 17 = 6.7647
you can also round it up to 6.8
Answer:
x=7
Step-by-step explanation:
Simplify both sides of the equation.
−8x−2x=7−11x
−8x+−2x=7+−11x
(−8x+−2x)=−11x+7(Combine Like Terms)
−10x=−11x+7
−10x=−11x+7
Add 11x to both sides.
−10x+11x=−11x+7+11x
ik this doesnt make sense but hope this helps
