Answer:

[tex]\frac{8}{\left(-x+2\right)^2}[/tex] & [tex]x = 1, x = 3[/tex]

Step-by-step explanation:

I'm sure you are familiar with the product rule,

If y = u*v => dy/dx = u * dv/dx + v * dy/dx <----- product rule

In this case:

[tex]u=3x+2,\:v=\left(2-x\right)^{-1},\\=>\frac{d}{dx}\left(3x+2\right)\left(2-x\right)^{-1}+\frac{d}{dx}\left(\left(2-x\right)^{-1}\right)\left(3x+2\right)[/tex]

Now remember the sum rule:

[tex]\frac{d}{dx}\left(3x+2\right) = \frac{d}{dx}\left(3x\right)+\frac{d}{dx}\left(2\right),\\\frac{d}{dx}\left(3x\right) = 3,\\\frac{d}{dx}\left(2\right) = 0\\\frac{d}{dx}\left(3x+2\right) = 3[/tex]

For this second bit we apply the chain rule:

[tex]\frac{d}{dx}\left(\left(2-x\right)^{-1}\right) = -\frac{1}{\left(2-x\right)^2}\frac{d}{dx}\left(2-x\right),\\\frac{d}{dx}\left(2-x\right) = -1,\\\\=> -\frac{1}{\left(2-x\right)^2}\left(-1\right)\\=> \frac{1}{\left(2-x\right)^2}[/tex]

If we substitute these values back into the expression...[tex]\frac{d}{dx}\left(3x+2\right)\left(2-x\right)^{-1}+\frac{d}{dx}\left(\left(2-x\right)^{-1}\right)\left(3x+2\right)[/tex]

...we get the following:

[tex]3\left(2-x\right)^{-1}+\frac{1}{\left(2-x\right)^2}\left(3x+2\right)[/tex]

The rest is just pure simplification:

[tex]3\left(2-x\right)^{-1}+\frac{1}{\left(2-x\right)^2}\left(3x+2\right)\\= \frac{3}{-x+2}+\frac{3x+2}{\left(-x+2\right)^2}\\= \frac{3\left(-x+2\right)}{\left(-x+2\right)^2}+\frac{3x+2}{\left(-x+2\right)^2}\\\\= \frac{3\left(-x+2\right)+3x+2}{\left(-x+2\right)^2}\\\\= \frac{8}{\left(-x+2\right)^2}[/tex]

Now let's equate this to equal 8 for the second bit and solve for x:

[tex]\frac{8}{\left(-x+2\right)^2}=8,\\\frac{8}{\left(-x+2\right)^2}\left(-x+2\right)^2=8\left(-x+2\right)^2,\\8=8\left(-x+2\right)^2,\\\left(-x+2\right)^2=1,\\x = 1, x = 3[/tex]

Answer:

Y = 3/2x + 8

Step-by-step explanation:

Slope (AKA M) can be found searching for each point on the graph. Since the graph starts at 8 it is the Y intercept (AKA B)

Answer: if they at 5 miles right now it should take 10 more miles to reach their target/ location

Answer:

1. The Pacific Ocean has an area of 63.78 million square miles, an average depth of 3,688 meters, and a volume of 660,000,000km cubed.

2. Use these guidelines when developing questions:

   Plan your questions.

   Know your purpose.

   Open conversation.

   Speak your listener's language.

   Use neutral wording.

   Follow general questions with specific ones.

   Focus your questions so they ask one thing at a time.

   Ask only essential questions.

3.  I don't know XD

4. On an adventure that humans don't know about

5. Depends on the picture of the sun.

6. They would probably be so confused while they tried to follow each other XD

Answer: $‭176.4‬0

Step-by-step explanation:

Keith mowed the yard 12 times.

Each time he mowed took 1.75 hours.

The number of hours he took in total is therefore:

= 12 * 1.75 hours

= 21 hours

He gets paid $8.40 for every hour he works. For the 21 hours therefore, he would earn:

= 8.40 * 21 hours

= $‭176.4‬0

Answer:

Tiffany purchase the better buy.

Step-by-step explanation:

given data

Tiffany paid  = $38

snowflake obsidian = 9 pounds

Tony paid = $19

same type of stone = 3 pounds

solution

Tiffany shopped well in this scenario. Mainly because Tiffany paid less per pound than Tony. This can be calculated by dividing the total amount paid by the amount received by each

so for Tiffany

= $38 ÷ 9

= $4.22 per pound

and for Tony  

=$19 ÷ 3

= $6.33 per pound

so that here Tiffany paid $4.22 per pound and Tony paid $6.33 per pound

so here whole $2.11 more than Tiffany

so that with this Tiffany purchase the better buy.

Answer:

(-12,3,5)

x=-12,y=3.z=5

Step-by-step explanation:

Answer:

130°

Step-by-step explanation:

Using the formula

Area of the triangle = 1/2 absin theta

a and b are the sides

theta is the obtuse angle

Given

a = 30m

b = 26m

Area = 200m²

Required

theta

Substitute into the formula;

300 = 1/2(30)*(26)sin theta

300 = 15*26sin theta

300 = 390 sintheta

sin theta = 300/390

sin theta = 10/13

sin theta = 0.7692

theta = arcsin(0.7692)

theta = 50.28degrees

Since the angle is obtuse, it must lie between 90 and 180degrees

theta = 180-50.28

theta = 129.72°

Hence the measure of the obtuse angle to the nearest degree is 130°

Answer:

3550 ft.

Step-by-step explanation:

y = 500(5) + 1050

  = 2500 + 1050

  = 3550 ft,

Step-by-step explanation:

so.......

y=20underroot 3

and X=20

Answer:

A and D and E

Step-by-step explanation:

Substitute the variable(in this case) t for 3, then use the order of operations to simplify(PEMDAS), which will give you 33 for both expressions. To see if two expressions are equivalent, you need to substitute the variable for an odd number AND an even number, so next, substitute the variable t for the number 6, which will give you 51 for both expressions. That means the expressions are equivalent

Hope this helps :)

P.S. Mark brainliest pls

Answer:

Step-by-step explanation:

Given expressions:

The value of both expressions when t=3 is 33.

The value of both expressions when t=3 is 23.

The value of both expressions when t=6 is 41.

The value of both expressions when t=6 is 51.

The two expressions are equivalent.

The two expressions are not equivalent.

Answer:

No, her reasoning is wrong

Step-by-step explanation:

Her reasoning is not correct because for one the expression clearly has a term. a/2 is a term on its own. So she concluding that a/2 isn't a term is quite wrong. Again, her basis for conclusion being that there exists no addition or subtraction signs makes the equation not being a term wrong, as well. Even though there isn't and subtraction nor addition sign, it does not stop it from being any less of a term

Answer:

Yes the triangles are similiar

Answer:

third option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x - 5 ← is in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (- 1, 1) into the partial equation

1 = - [tex]\frac{1}{2}[/tex] + c ⇒ c = 1 + [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{2}[/tex]

y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← equation of perpendicular line
