Answer:

y-3

Step-by-step explanation:

4(y-3) + 9 - 3y

Use distributive property for 4(y-3)

= 4y-12+9-3y

Then simplify

= 4y-3y-12+9

= y-3

A vehicle factory manufactures cars. The unit cost C (the cost in dollars to make each car) depends on the number of cars made.

Snezhnost [94]

Answer:

The minimum unit cost is 5377

Step-by-step explanation:

Note that we have a cudratic function of negative principal coefficient.

The minimum value reached by this function is found in its vertex.

For a quadratic function of the form

$ax ^ 2 + bx + c$

the x coordinate of the vertex is given by the following expression

$x=-\frac{b}{2a}$

In this case the function is:

$C(x) = x^2 - 400x + 45,377$

So:

$a=1\\b=-400\\c=45,377$

Then the x coordinate of the vertex is:

$x=-\frac{-400}{2(1)}$

$x=200\ cars$

So the minimum unit cost is:

$C(200) = (200)^2 - 400(200) + 45,377$

$C(200) = 5377$
