Answer:

<h2><u><em>x = 7</em></u></h2>

Step-by-step explanation:

Solve

6(x - 3) = 2x + 10

6x - 18 = 2x + 10

6x - 2x = 10 + 18

4x = 28

x = 28 : 4

x = 7

--------------------

check

6(x - 3) = 2x + 10

6(7-3) = 2 * 7 + 10

24 = 24

the answer is good

Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.
adoni [48]

Answer: The required derivative is \dfrac{8x^2+18x+9}{x(2x+3)^2}

Step-by-step explanation:

Since we have given that

y=\ln[x(2x+3)^2]

Differentiating log function w.r.t. x, we get that

\dfrac{dy}{dx}=\dfrac{1}{[x(2x+3)^2]}\times [x'(2x+3)^2+(2x+3)^2'x]\\\\\dfrac{dy}{dx}=\dfrac{1}{[x(2x+3)^2]}\times [(2x+3)^2+2x(2x+3)]\\\\\dfrac{dy}{dx}=\dfrac{4x^2+9+12x+4x^2+6x}{x(2x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{8x^2+18x+9}{x(2x+3)^2}

Hence, the required derivative is \dfrac{8x^2+18x+9}{x(2x+3)^2}

The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $
love history [14]
$1.50C + $4A= $5050
 C + A = 2200

-4(C + A = 2200)
-4C - 4A = -8800
1.50C+4A = 5050
-----------------------
-2.5C =- 3750
-2.5C/-2.5 =- 3750/-2.5
C = 1500

C + A = 2200
1500 + A =2200
1500 - 1500 + A = 2200 - 1500
A = 700

CHECK
$1.50C + $4A= $5050
$1.50(1500) + $4(700)= $5050
$2250 +$2800 =$5050
$5050 = $5050

 C + A = 2200
1500 + 700 =2200
2200 = 2200
