first one
Step-by-step explanation:
first one
Answer:
We know that our triangle has one side along the line:
y = (1/4)*x
And other side along the line:
y = -(1/4)*x.
Now, we want to find the vertex.
And we know that the vertex is the point where the two sides conect, so the vertex must be a common point of both lines.
Then we have:
y = (1/4)*x = -(1/4)*x
x = -x
The only solution to that equation is x = 0.
now we evaluate our lines in x = 0 and get:
y = (1/4)*0 = 0
y = -(1/4)*0 = 0
Then the lines intersect in the point (0, 0)
Then the vertex must be in the point (0, 0)
Answer:
18 smaller bags
Step-by-step explanation:
Each one pound bag becomes 3 one-third pound bags.
So 6 one pound bags will become 6×3=18 one-third pound bags.
Answer:
Step-by-step explanation:
The vertex equation of a parabola is y - k = m(x - h)^2. This can be rewritten as y = a(x - h)^2 + k. Comparing this formula with the given f(x) = 9(x - 5)2 + 6, we see immediately that h = 5, k = 6 and a = 9. The vertex is at (h, k): (5, 6).
