find the derivative in the form dy/dx

Answer:

x = 4

Step-by-step explanation:

Given

4x - 6 + 2x = 18 ← simplify left side by collecting like terms

6x - 6 = 18 ( add 6 to both sides )

6x = 24 ( divide both sides by 6 )

x = 4

The solution to the equation 4x - 6 + 2x = 18 is x = 4.

To solve the equation 4x - 6 + 2x = 18, we need to combine like terms and isolate the variable x.

First, let's combine the like terms on the left side of the equation:

4x + 2x - 6 = 18

This simplifies to:

6x - 6 = 18

Next, we can isolate the variable x by adding 6 to both sides of the equation:

6x - 6 + 6 = 18 + 6

This simplifies to:

6x = 24

To solve for x, we can divide both sides of the equation by 6:

(6x)/6 = 24/6

This simplifies to:

x = 4

Therefore, the solution to the equation 4x - 6 + 2x = 18 is x = 4.

Answer:

5.29

Step-by-step explanation:

bearing in mind that the average rate of change = slope, and for that we can simply use two points off the table.

[tex]\bf \begin{array}{|cc|ll} \cline{1-2} x&y\\ \cline{1-2} -2&12\\ 0&3\\ 3&-10.5\\ 7&-28.5\\ \cline{1-2} \end{array}\qquad \qquad \begin{array}{llll} (\stackrel{x_1}{-2}~,~\stackrel{y_1}{12})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-10.5}) \\\\\\ slope \implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-10.5-12}{3-(-2)} \\\\\\ \cfrac{-10.5-12}{3+2}\implies \cfrac{-22.5}{5}\implies -\cfrac{4.5}{1}\implies -4.5 \end{array}[/tex]

The rate of change of y with respect to x for the given function with coordinates expressed in the table is; dy/dx = -9/2

The rate of change of y with respect to x for a given linear function is simply the slope expressed as;

dy/dx = (y2 - y1)/(x2 - x1)

Let us take the first 2 coordinates which are;

(-2, 12) and (0, 3)

Thus;

dy/dx = (3 - 12)/(0 - (-2))

dy/dx = -9/2

Or dy/dx = -4.5

Answer:

slope rise 3 run 2 1/2

Step-by-step explanation:

if you start from the bottom and if you start from the top it's -3 and -2 1/2

Answer: The slope is 3 and the y-intercept is 3/2

Step-by-step explanation:

The slope of a linear function can be calculated as:

s = (y2 - y1)/(x2 - x1)

Where y2 = f(x2) and y1 = f(x1) and f(x) is the linear function.

So here we can use any two pairs of the set of data, for example, the first two.

(-1 , -3/2) and (-1/2,0)

s = (0 -(-3/2))/(-1/2 - (-1)) = (3/2)/(1/2) =(3/2)*(2/1) = 3

So the slope is equal to 3.

the y-intercept is the value of y when x = 0, in the table we can see that when x = 0. the value of y = 3/2

So the function is: y = 3*x + 3/2

and the correct option is the fourth one.

Answer:

Option D.

Step-by-step explanation:

A line will be in the form of y = mx + c

Where m = slope of the line and c = y-intercept

In this question slope of the line is given as [tex]\frac{1}{2}[/tex] and it passes through origin.

Since line passes through origin then there will be no y-intercept that means c=0

So equation will be y = [tex]\frac{1}{2}[/tex]x

Now check each option that satisfy the equation of the line.

Option A. ( 0, [tex]\frac{1}{2}[/tex] )

                 y = 0 ≠ [tex]\frac{1}{2}[/tex] so invalid option

Option B. ( [tex]\frac{1}{2}[/tex], 1 )

               y = [tex](\frac{1}{2})[/tex] [tex](\frac{1}{2})[/tex] = [tex](\frac{1}{4})[/tex] ≠ 1 Invalid option

Option C. ( 1,2)

Divide each side by 2 pi

24π/2π =2π/2π(r^2+r)

12 = r^2 +r

Subtract 12 from each side

12-12 = r^2 +r -12

0 =  r^2 +r -12

4-3 = 1

0= (r+4) (r-3)

Using the zero product property

r+4 =0          r-3 =0

r+4-4 =0-4   r-3+3=0+3

r = -4           r = -3

The angles circled in red below are same side exterior. This means that the sum of them is 180 degrees. You can make a formula like so that you will solve for x...

98 + x = 180

98 - 98 + x = 180 - 98

0 + x = 82

x = 82

Another way to solve:

The angles circled in pink below are opposite side exterior. This means that they must equal each other...

Answer:

2W+3  I am really sorry if that's wrong, I don't think it is though GOODLUCK

Step-by-step explanation:

Answer:

The correct answer is option A.   2w + 3

w = 5 inches

Step-by-step explanation:

It is given that, the length of a rectangle is 3 inches more than twice its width, and its area is 65 square inches.

To find the correct option

If 'w' is the width of rectangle, then length = 3 inches more than the twice the width

length   = 2w + 3

The correct answer is option A.   2w + 3

To find the width

We have area = 65 square inches

Length * Width = 65

(2w + 3) * W = 65

2w² + 3w - 65 = 0

Solving we get ,

w = 5 and -6.5

Therefore w = 5 inches

Answer:

x = 2

Step-by-step explanation:

Using the rules of logarithms

• log [tex]x^{n}[/tex] ⇔ nlog x

• log x + log y ⇔ log(xy)

• log x = log y ⇒ x = y

Given

3 ln2 + ln8 = 2ln(4x)

ln2³ + ln8 = ln(4x)²

ln8 + ln8 = ln16x²

ln(8 × 8) = ln16x²

ln64 = ln16x², hence

16x² = 64 ( divide both sides by 16 )

x² = 4 ( take the square root of both sides )

Final answer:

To complete the square for the equation x² - 9x + _____ = 6, the constant term should be (81/4). This is obtained by dividing the coefficient of x by 2 and then squaring it.

Explanation:

The constant term required to complete the square for the equation x² - 9x + _____ = 6 can be found using a specific algebraic method. To complete the square, the coefficient of the x term should be divided by 2 and then squared. Therefore, for the equation provided, we take (-9/2) and square it, which results in (81/4). The complete equation after adding the constant term will be x² - 9x + 81/4 = 6 which, after completing the square, can be written as (x - 9/2)² = 6 + 81/4.

Answer:

5, 11,17,23,29

Step-by-step explanation:

To obtain the term in the sequence add the common difference to the previous term, that is

a(1) = 5

a(2) = 5 + 6 = 11

a(3) = 11 + 6 = 17

a(4) = 17 + 6 = 23

a(5) = 23 + 6 = 29

The first five terms of an arithmetic sequence starting with 5 and a common difference of 6 are 5, 11, 17, 23, and 29.

The first five terms of the arithmetic sequence with the first term 5 and a common difference of 6 can be found by successively adding the common difference to the previous term.

Third term (a3) = a2 + 6 = 11 + 6 = 17

Fifth term (a5) = a4 + 6 = 23 + 6 = 29

Therefore, the first five terms of the arithmetic sequence are 5, 11, 17, 23, and 29.

Answer:

$878.25

Step-by-step explanation:

Continuously compounded interest is:

A = Pe^(rt)

where A is the final amount, P is the initial amount, r is the interest rate, and t is the number of compoundings.

Here, P = 560, r = 0.09, and t = 5.

A = 560e^(0.09×5)

A = 878.25

Final answer:

To calculate the future value of an investment compounded continuously, use the formula A = Pert. In this case, the investment will be worth approximately $877.29 in 5 years.

Explanation:

To calculate the future value of an investment compounded continuously, we can use the formula A = Pert, where A is the future value, P is the initial principal, r is the annual interest rate, and t is the time in years. In this case, P = $560, r = 0.09, and t = 5. Plugging these values into the formula, we get:

A = 560e^(0.09⋅5)

A ≈ 560e^0.45

A ≈ 560 ⋅ 1.5662

A ≈ $877.29

Therefore, the investment will be worth approximately $877.29 in 5 years.
