Answer:
Its -2
Step-by-step explanation:
Let's solve your equation step-by-step.
−12−4x+3=−1
Step 1: Simplify both sides of the equation.
−12−4x+3=−1
−12+−4x+3=−1
(−4x)+(−12+3)=−1(Combine Like Terms)
−4x+−9=−1
−4x−9=−1
Step 2: Add 9 to both sides.
−4x−9+9=−1+9
−4x=8
Step 3: Divide both sides by -4.
−4x
−4
=
8

Answer:
Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644
Step-by-step explanation:
The cost equation is given as:

This is a quadratic equation in general form, which is:

Matching, we can say:
a = 0.04
b = -5
c = 800
The minimum occurs at 
and the minimum value would be to place that "x" value into the equation.
First, we find the minimum using values of a and b:

Plugging this into original, we get:

Rounding off to nearest whole number, we can say:
Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644
The unit rate will be in revolutions per second. That means divide number of revolutions by number of seconds.
first convert from mixed fraction.
6 2/5 = 32/5 revolutions
2 2/3 = 8/3 seconds
32/5 ÷ 8/3
flip multiply
32/5 × 3/8 = 12/5 revolutions per second
12/5 = 2 2/5 revolutions per second
