Answer:
B) 
Step-by-step explanation:
To find the function which has vertex at the origin.
Solution:
For a function to have its vertex at origin the function must pass through point (0,0) which means 
.
We will find 
for each of the given functions and check if it has vertex at origin.
To find we will plugin 
in the function.
A) 
Vertex is not at the origin.
B)
[Any number times zero is = zero]
Vertex is at the origin.
C) 
Vertex is not at the origin.
D) 
Vertex is not at the origin.
They're not congruent.
If you count the numbers between AC and BE, they're different.
AC - goes from -7 to 0, which is 7 spaces
BE - goes from -2 to 6, which is 8 spaces
Answer:
I believe the answer is 2. You may want to get a second opinion though because Im not sure
Y = -2.8x +69.4
Let y represent units of inventory, and x represent days since the last replenishment. We are given points (x, y) = (3, 61) and (13, 33). The line through these points can be described using the 2-point form of the equation of a line:
... y -y1 = (y2-y1)/(x2 -x1)(x -x1)
Filling in the given point values, we have ...
... y -61 = (33 -61)/(13 -3)(x -3)
Simplifying and adding 61, we get ...
... y = -2.8x +69.4
