What is the value of x?

Answer:

n= -4

Step-by-step explanation:

First we have to find the equation of line which passes through (6,3) and (8,4).

Then we have to pass this line through the point (n , -2).

we know, equation of line passing through (x1,y1) and (x2,y2) is

[tex]\frac{x-x1}{x1-x2}=\frac{y-y1}{y1-y2}[/tex]

So, the equation of line passing through (6,3) and (8,4) is

[tex]\frac{x-6}{6-8}=\frac{y-3}{3-4}[/tex]

or, [tex]\frac{x-6}{-2} =\frac{y-3}{-1}[/tex]

multiplying both sides by  -2

x-6=2(y-3)

or, x-6=2y-6

or, x-2y=6-6

or, x-2y=0

Now, we have to pass this line through  (n,-2)

So, using the point in the line, that is using  x=n  , y=-2

we get

n-2(-2)=0

or, n+4=0

or, n=-4

Answer:

Step-by-step explanation:

Given that the line passes through

(6,3), (8,4), and (n,-2).

We have to find the value of n.

Let us name the points as A, B and C in that order

Slope of AB = slope of BC since all 3 points lie in the same line

To find slope of AB:

Slope = (y2-y1)/(x2-x1) = (4-3)/(8-6) = 1/2

To find slope of BC:

Using the same formula slope = (-2-4)/(n-8) = -6/(n-8)

The two slopes are equal.

Hence 1/2 = -6/(n-8)

n-8 = -12

n = -4

Hello!

The approximate volume of the cylinder is the second option: 59.3 [tex]ft^{3}[/tex]

V = [tex]\pi r^{2} h[/tex]

V = 3.14 * 3^2 * 2.1

V = 3.14 * 9 * 2.1

V = 59.346 [tex]ft^{3}[/tex]

Final answer:

Explanation of calculating the volume of a cylinder with given radius and height using the formula V = πr²h.

Explanation:

The volume of a cylinder can be calculated using the formula V = πr²h. Given a radius of 3 feet and a height of 2.1 feet, when plugged into the formula with π = 3.14, the volume is approximately 19.74 cubic feet.

If 4 - 3 + 5 = -6 + 8 + 4 is a mathematically correct statement, then both sides should end up with the same number:

4 - 3 + 5 = -6 + 8 + 4     Original statement.

1 + 5 = -6 + 8 + 4     You can do this in any order, but I start by doing the 4 - 3.

6 = -6 + 8 + 4     Finish simplifying the left side.

6 = 2 + 4     Combine the -6 and 8.

6 = 6     Finish simplifying the right side.

Because both sides are equal to each other, the sentence must be true.

Therefore, the sentence is true because when simplified, the statement is 6 = 6.

Hope this helps! :)

EDIT: Just incase anyone is curious, both this way and the way the other guy used both work, as they both prove that both sides are equal.

Assuming that the question is "11 times 6" rather than "11x times 6". The answer would be 66.

The equation for this problem is: 11 + (11 x 6) - 11)

"11 more than" means you would add 11 to the next equation. "11 less than" means you would subtract 11 from the following equation.

According to Order of Operations, you would start with the expressions in the parenthesis. So we would start with "11 x 6", which is 66. Then the expression would become 11 + (66 - 11). We would do the expression the parenthesis, "66 - 11", and we would get the answer 55. The expression would become 11 + 55, and 11 + 55 is 66.

The arithmetic statement '11 more than 11 less than (11x6)' first requires you to do the multiplication, resulting in 66, then subtract 11 to get 55, and finally add 11 to get 66.

The mathematical statement "11 more than 11 less than (11x6)" is an arithmetic problem that requires several steps to solve. Firstly, compute the values in brackets. You must multiply 11 by 6, which results in 66. The next step is to understand what '11 less than' means. It means to subtract 11 from 66, which gives you 55. Then you interpret the last part of the statement: '11 more than', which means you add 11 to that 55. This finally gives you a sum of 66.

The two integers between which the cube root of 50 lies are 3 and 4.

To find the two integers between which the cube root of 50 lies, we can start by evaluating the cube roots of consecutive integers until we find the two integers that enclose the cube root of 50.

Let's calculate the cube roots of some consecutive integers:

Cube root of 1: 1

Cube root of 2: 1.25992

Cube root of 3: 1.44225

Cube root of 4: 1.58740

Cube root of 5: 1.70997

Cube root of 6: 1.81712

Cube root of 7: 1.91293

Cube root of 8: 2

Cube root of 9: 2.08008

Cube root of 10: 2.15443

We can observe that the cube root of 50 is greater than the cube root of 27 (which is approximately 3), and less than the cube root of 64 (which is 4). Therefore, the cube root of 50 lies between 3 and 4.

Hence, the two integers between which the cube root of 50 lies are 3 and 4.

Step-by-step explanation:

rise = 6

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

run = 1

Rise is the y axis and run is the x axis. You look at the point and first go either up or down to the point you need to stop at. In this case we go down. Run is when you go sideways. Once you reach the line where the point lies, you need to go sideways 1 time to get to the point. Since rise is over run, 6 over 1

Therefore...........

6 over 1 = 6!!!!

Using partial quotients is a method of dividing where you break the DIVIDEND into sections that are easy to divide

The complex numbers are [tex]\(5i - 2\)[/tex] and [tex]\(5i + 2\)[/tex], meeting the conditions: sum [tex]\(10i\)[/tex], difference [tex]\(-4\)[/tex], product [tex]\(-29\)[/tex].

Let's denote the two complex numbers as [tex]\(a\)[/tex] and [tex]\(b\)[/tex].

Given:

1. [tex]\(a + b = 10i\)[/tex]

2. [tex]\(a - b = -4\)[/tex]

3. [tex]\(a \times b = -29\)[/tex]

From the first equation, we can isolate one variable in terms of the other:

[tex]\[ a = 10i - b \][/tex]

Now, substitute this expression for [tex]\(a\)[/tex] into the second and third equations:

[tex]\[ (10i - b) - b = -4 \][/tex]

[tex]\[ 10i - 2b = -4 \][/tex]

[tex]\[ 2b = 10i + 4 \][/tex]

[tex]\[ b = 5i + 2 \][/tex]

Now that we have found [tex]\(b\)[/tex], we can substitute it back into the expression for [tex]\(a\)[/tex] to find [tex]\(a\)[/tex]:

[tex]\[ a = 10i - (5i + 2) \][/tex]

[tex]\[ a = 10i - 5i - 2 \][/tex]

[tex]\[ a = 5i - 2 \][/tex]

So, the two complex numbers are [tex]\(5i - 2\)[/tex] and [tex]\(5i + 2\)[/tex]. Both of these satisfy the given conditions.

the answer to your question is D

Answer:  the correct option is

(D) (-7, -1), 6 units.

Step-by-step explanation:  We are given to find the co-ordinates of the center and the length of the radius of the following circle :

[tex]x^2+y^2+14x+2y+14=0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We know that

the STANDARD equation of a circle with center at the point (h, k) and radius of length r units is given by

[tex](x-h)^2+(y-k)^2=r^2.[/tex]

From equation (i), we have

[tex]x^2+y^2+14x+2y+14=0\\\\\Rightarrow (x^2+14x+49)+(y^2+2y+1)+14-49-1=0\\\\\Rightarrow (x+7)^2+(y+1)^2-36=0\\\\\Rightarrow (x+7)^2+(y+1)^2=36\\\\\Rightarrow (x-(-7))^2+(y-(-1))^2=6^2.[/tex]

Comparing the above equation with the standard equation of a circle, we get

center, (h, k) = (-7, -1)  and radius, r = 6 units.

Thus, (D) is the correct option.

Hey there!!

Given equation :

... c(x) = 29x + 54.5

In this equation $54.50 is installation fee and this would remain as a constant. ( This value wouldn't change ).

'x' is represented as the number of months.

The total cost or c(x) is given as $344.50

Getting this into equations :

... 344.50 = 29x + 54.5

Subtracting 54.5 on both sides :

... 29x = 290

Dividing by 29 on both sides :

... x = 10

Hence, the number of months is 10.

Hope my answer helps!!

By manipulating the provided cost function, we find that with $344.50, you can afford 10 months of cable service.

To determine the number of months of cable service you can have for $344.50, you simply need to solve the equation C(x) = 29x + 54.5 = 344.5, where C(x) represents the cost of the service and x is the number of months you are paying for. We can start by subtracting the installation fee (54.5) from both sides of the equation, which gives us 29x = 290. Then, dividing through by 29, we arrive at x=10.

Therefore, you can have cable service for 10 months if you have $344.50.
