6 - 2/3(×+5) =4× plz answer

Diano4ka-milaya [45]

Answer:

$x = \frac{4}{7}$

Step-by-step explanation:

Here, the given expression is : $6 - \frac{2}{3}(x+5) = 4x$

Solving for x:

$6 - \frac{2x}{3} - 5(\frac{2}{3}) = 4x$

$6 - \frac{10}{3} = 4x + \frac{2x}{3} \\or, \frac{18 - 10}{3} = \frac{12x + 2x}{3}$

⇒ 8 = 14x

⇒ x = 8/14

or, $x = \frac{8}{14} = \frac{4}{7}$

Answer: $\$18,629$

Step-by-step explanation:

Given

The unit cost is given by

$C(x)=0.6x^2-168x+30,389$

find the derivative of the unit cost and equate it to zero to obtain the minimum value

$C'(x)=0.6\times 2x-168\\\Rightarrow 0.6\times 2x-168=0\\\Rightarrow 1.2x=168\\\\\Rightarrow x=\dfrac{168}{1.2}\\\\\Rightarrow x=140$

Substitute 140 for $x$ in the cost function, we get

$C(140)=0.6[140]^2-168(140)+30,389\\C(140)=11,760-23,520+30,389\\C(140)=\$18,629$
