\huge\text{Hey there!}

\huge\text{-6(n - 8) = 4(12 - 5n)}

\huge\text{First, \bf{distribute}}\text{ the terms}

Formula is: a ( b + c) = a(b) + a(c) = ab + ac  

\huge\text{First set}\downarrow

\text{-6(n - 8)}\\\text{-6(n) - 6(-8)}\\\text{-6(n) = -6n}\\\text{-6(-8) = 48}\\\boxed{\text{Result for the left side:-6n +48}}

\huge\text{Second set}\downarrow

\text{4(12-n)}\\\text{4(12 - 5n)}\\\text{4(12)-4(-5n)}\\\text{4(12) = 48}\\\text{4(-5n) = -20n}\\\boxed{\text{Result for the right side 48 + (-20)}}

\text{We get:-6n +48 +20n=-20n+ 48+ 20n}

→ = 14n+48 = 48

\huge\text{Now, you have to SUBTRACT by 48 on your}\\\huge\text{sides.}

\text{14n + 48 \bf{ - 48}}\text{ = 48 - \bf{48}}

\text{Cancel out the second: 48 - 48 because it equals 0}

\text{Keep the first one because it helps us solve for our answer}

\text{14n = 0}\\\text{Divide both sides by the number \bf{14}}

\dfrac{\text{14n}}{14} = \dfrac{0}{14}\\\\\text{Cancel out}\dfrac{\text{14n}}{14}\text{ because it equals to one and we don't need it for this problem}\\\\\\\text{Keep: }\dfrac{0}{14}\text{ because it helps us solve for our answer.}

\dfrac{0}{14}=0\div14 = 0\\\\\boxed{\boxed{\text{Answer: \bf{ n = 0}}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}

Answer:

0

Step-by-step explanation:

-6(n-8) = 4(12-5n)+14n

-6(n-8)=-6n+48 =  4(12-5n)+14n= 48-20n+14n

then 48-20n+14n<em> = 48-6n</em>

so you have

-6n+48 = <em>48-6n</em>

-6n+6n= n

n+48=48

n-48=48-48

n=0

Use the table below to determine whether f(x) could represent a linear function If it could write f(x) in the form f(x)=mx+b
Elodia [21]

Answer:

  • f(x) = 6x - 5

Step-by-step explanation:

We see f(x) increase is linear and is 6 at each step, so m = 6 and y-intercept is b = -5, from point (0, -5)

<u>So the function is:</u>

  • f(x) = 6x - 5

A car rental agency has 150 cars. The owner finds that at a price of $48 per day, he can rent all the cars. For each $2 increase
hram777 [196]
Given that for each <span>$2 increase in price, the demand is less and 4 fewer cars are rented.

Let x be the number of $2 increases in price, then the revenue from renting cars is given by
(48 + 2x) \times (150 - 4x)=7,200+108x-8x^2.

Also, given that f</span><span>or each car that is rented, there are routine maintenance costs of $5 per day, then the total cost of renting cars is given by
5(150-4x)=750-20x

Profit is given by revenue - cost.
Thus, the profit from renting cars is given by
</span><span>(7,200+108x-8x^2)-(750-20x)=6,450+128x-8x^2

For maximum profit, the differentiation of the profit function equals zero.
i.e.
</span><span>\frac{d}{dx} (6,450+128x-8x^2)=0 \\  \\ 128-16x=0 \\  \\ x= \frac{128}{16} =8

The price of renting a car is given by 48 + 2x = 48 + 2(8) = 48 + 16 = 64.

Therefore, the </span><span>rental charge will maximize profit is $64.</span>
