Answer:
Step-by-step explanation:
Think of the ">" as an equal sign. So, y=-4x+1. You need to plot the y-intercept, which is (0,1). Go down 4 and to the right 1. Plot the point. Keep doing this. If you want to do it the opposite way, go up 4 and to the left right.
Answer: A
Step-by-step explanation: 6 is for $4 therefore 3 is for $2
Answer:
Minimum Unit Cost = $14,362
Step-by-step explanation:
The standard form of a quadratic is given by:
ax^2 + bx + c
So for our function, we can say,
a = 0.6
b = -108
c = 19,222
We can find the vertex (x-coordinate where minimum value occurs) by the formula -b/2a
So,
-(-108)/2(0.6) = 108/1.2 = 90
Plugging this value into original function would give us the minimum (unit cost):
