5x + 4 = 7x + 2
Subtract 5x from both sides.
4 = 2x + 2
Subtract 2 from both sides.
2 = 2x
Divide both sides by 2.
1 = x
OOOOH my favorite LONG DIVISION but anyways the answer is 164.4
Answer:
An independent variable is changed or controlled in an experiment, while a dependent variable is being tested and measured.
love your profile pic btw!
The number of machines that must be made to minimize the unit cost will be 230.
<h3>How to calculate the units?</h3>
From the information, the cost function is given as C(x)=0.9x²-414x+52,794. This will be differentiated.
C(x)=0.9x²-414x+52,794
C'(x) = d/dx(0.9x² - 414x + 52,794)
= 1.8x - 414
1.8x - 414 = 0
1.8x = 414
x = 414/1.8
x = 230
