Answer
-2/2
Step-by-step explanation:
7x + 12 = 12
-12 -12
subtract 12 from both sides of the equation as seen above
7x = 0
divide both sides by 7 to isolate the variable
x = 0
B is the correct option.
The answer to thus problem is 269. 7
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
