6x-3-11-8x=2 please show work

Ludmilka [50]

Answer: is x = -8

this is how i got it ______

6 x - 3 - 11 - 8 x = 2

(simplify both sides and combine like terms)

(6x + -8x ) + ( -3 + -11) = 2

- 2x + -14 = 2

-2x - 14 = 2

( then you add 14 to both sides)

- 2x - 14 = 2

+14 +14

-2x = 16

( then you divide both sides by -2)

-2x / -2 = 16/ -2

x = -8

ta da!! happy to help!

it made it here. this is for the second one.

( first, we subtract 8n from both sides)

13n + 26 = 8n - 29

-8n -8n

5n + 26 = -29

( then we subtract 26 from both sides)

5n + 26 = -29

- 26 -26

5n = - 55

(after that we divide both sides by 5, we do this to make n alone )

5n/ 5 = -55/ 5

n = -11

Study the given values of the data and then choose the best suitable answers for all the questions.

Answer:

Mean = 18 and Mode = 10

Step-by-step explanation:

The given data is :

10,10, 18, 24,28

We can find the mean of the data,

$Mean=\dfrac{\text{sum of observations}}{\text{total no of observations}}$

$M=\dfrac{10+10+18+24+28}{5}\\\\=18$

Mode is the repetition of data.

Here, 10 repeats 2 times.

So, the mode is 10.

Give the ellipse 9x² + 16y2 = 144, find the equation of the diameter which bisects the chord with slope 1/2

Genrish500 [490]

The equation of the diameter which bisects the chord with slope 1/2 is

$y=-\frac{9}{8} x$

The general form of the equation of given ellipse is $ax^2+by^2=c$ and equation of chord will be $y=mx+n$ for some m and n.

Now in order to find values of x that intercept the ellipse it must fulfill the equation as such;

$ax^2+b(mx+n)^2=c$

$(a+bm^2)x^2+2bmnx+bn^2 - c=0$

<h3 /><h3>What is the definition of an ellipse?</h3>

It is a plane section curve whose sum from two fixed points will be a constant value.

Quadratic roots will give the mid value of x and value of y will be ;

$X=\frac{-b}{2a} =\frac{-bmn}{a+bm^2}$

$Y=n-\frac{bm^2n}{a+bm^2} =\frac{an}{a+bm^2}$

Thus the final equation of required diameter will be :

$y=\frac{Y}{X} x=-\frac{a}{bm} x$

And in this case the equation of the diameter which bisects the chord with slope 1/2 is,

$y=-\frac{9}{8} x$
