Log_{7 }(5 - 3x) Find the derivative

V125BC [204]

Let y be the expression you want to differentiate:

$y=\log_7(5-3x) \implies 7^y=5-3x$

Now,

$7^y=e^{\ln(7^y)}=e^{y\ln(7)}$

Use the chain rule to differentiate both sides with respect to x :

$\ln(7)e^{y\ln(7)}\dfrac{\mathrm dy}{\mathrm dx}=-3$

Solve for dy/dx :

$\ln(7)7^y\dfrac{\mathrm dy}{\mathrm dx}=-3$

$\dfrac{\mathrm dy}{\mathrm dx}=-\dfrac3{\ln(7)7^y}$

$\dfrac{\mathrm dy}{\mathrm dx}=\boxed{-\dfrac3{\ln(7)(5-3x)}}$

Maddie has a gross monthly income of $2200. She has 35% of her paycheck withheld as deductions.

Softa [21]

Answer:

The percent of net income Maddie gives as rent = 29.97%

Step-by-step explanation:

Given:

Gross monthly income for Maddie = $2200

Percentage of her paycheck withheld = 35%

Amount paid for rent = $400

To find the percent of her net monthly pay that goes to rent.

Solution:

Amount of paycheck withheld as deductions :

⇒ 35% of the gross income

⇒ 35% of $2200

⇒ $0.35\times $2200$

⇒ $ 770

Net income = Gross income - deductions =  $\$2200-\$770$ = $1430

Percentage of net income given as rent is given as :

⇒ $\frac{Amount\ given\ as\ rent}{Net\ income}\times 100$

⇒ $\frac{400}{1430}\times 100$

⇒ 27.97% (Answer)
