1)what is the measure of the segment AB
2)what is the measure of segment CD
how so?

Answers

Answer:

AB = 18, CD = 16

Step-by-step explanation:

The 3 segments make the whole line , that is

AB + BC + CD = AD , substitute values

AB + 20 + (BD - BC) = 54

AB + 20 + (36 - 20) = 54

AB + 20 + 16 = 54

AB + 36 = 54 ( subtract 36 from both sides )

AB = 18

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

BC + CD = BD , substitute values

20 + CD = 36 ( subtract 20 from both sides )

CD = 16

Point C is located between points B and D. Also BC = 5x + 7, CD = 3y + 4, BD = 38, and BD = 2x + 8y. Find the values of x and y

Answers

Using location of points and a system of equations, it is found that:

The value of x is 3.The value of y is 4.

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

Point C is located between points B and D means that:

[tex]BD = BC + CD[/tex]

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

We are given that:

[tex]BC = 5x + 7[/tex][tex]CD = 3y + 4[/tex][tex]BD = 38[/tex][tex]BD = 2x + 8y[/tex]

From this, two equations can be built.

[tex]2x + 8y = 38[/tex]

Dividing both sides by 2:

[tex]x + 4y = 19[/tex]

[tex]x = 19 - 4y[/tex]

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

Finding y:

[tex]BC + CD = BD[/tex]

[tex]5x + 7 + 3y + 4 = 38[/tex]

[tex]5x + 3y + 11 = 38[/tex]

[tex]5x + 3y = 27[/tex]

Since [tex]x = 19 - 4y[/tex]

[tex]5(19 - 4y) + 3y = 27[/tex]

[tex]95 - 20y + 3y = 27[/tex]

[tex]17y = 68[/tex]

[tex]y = \frac{68}{17}[/tex]

[tex]y = 4[/tex]

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

Finding x:

[tex]x = 19 - 4y = 19 - 4(4) = 19 - 16 = 3[/tex]

The value of x is 3.

The value of y is 4.

find the coordinates of the points of intersection of the line 2x+3y+2=0 with the curve 2xy=-1

no spam plz fast

Answers

Make y the subject of the curve equation
y = -1/(2x)
Substitute for y in the line equation
2x +3(-1/2x) + 2 = 0
Multiply every term by 2x
4x^2 - 3 + 4x = 0
4x^2 + 4x - 3 = 0
(2x - 1)(2x + 3) = 0
If 2x - 1 = 0 then
2x = 1
x = 1/2
y = -1/(2 x 1/2) = -1

If 2x + 3 = 0 then
2x = -3
x = -1.5
y = -1/(2 x -1.5) = -1/3

The points of intersection are (1/2, -1) and (-1.5, -1/3)

Sorry about the mixture of fractions and decimals ;)

The point of intersection of the line 2x+3y+2=0 with the curve 2xy = -1 will be (1/2, - 1) and (1/6, 1/3).

What is substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The equation of lines are,

⇒ 2x + 3y + 2 = 0

⇒ 2xy = - 1

Now,

Since, The equation of lines are,

⇒ 2x + 3y + 2 = 0  ..(i)

⇒ 2xy = - 1   ..(ii)

From (ii);

⇒ 2xy = - 1

⇒ x = - 1/2y

Put above value in (i), we get;

⇒ 2 × - 1/2y + 3y + 2 = 0

⇒ - 1/y + 3y + 2 = 0

⇒ - 1 + 3y² + 2y = 0

⇒ 3y² + 2y - 1 = 0

⇒ 3y² + 3y - y - 1 = 0

⇒ 3y (y + 1) - 1 (y + 1) = 0

⇒ (3y - 1) (y + 1) = 0

⇒ y = 1/3

And, y = - 1

So, The value of x is,

⇒ x = - 1/2y

⇒ x = - 1/2 × - 1

⇒ x = 1/2

And, x = - 1/2 × 1/3

⇒ x = 1/6

Thus, The intersection point on the lines = (1/2, - 1) and (1/6, 1/3)

square root of the quantity x minus 2 end quantity plus 8 equals x

solve for x

Answers

Answer:

x = 11.

Step-by-step explanation:

√(x - 2) + 8 = x

√(x - 2) = x - 8

Square both sides:

x - 2 = (x - 8)^2

x - 2 =  x^2 - 16x + 64

x^2 - 17x + 66 = 0

(x - 6)(x - 11) = 0

x = 6, 11.

With this type of question we could have extraneous roots so:

Check these 2 roots:

x = 6:

√(2 - 6) + 8 = √(-4)+8   <----- has no real value so this is not a root,

x = 11:

√(11-2) + 8 = 11    <  ----Checks out.

Answer:

x = {6, 11}

Step-by-step explanation:

[tex]\sqrt{x-2} + 8=x[/tex][tex]\sqrt{x-2} = x - 8[/tex]x - 2 = (x - 8)²x² - 16x + 64 = x - 2x² - 17x + 66 = 0x = (17 ± [tex]\sqrt{17^2- 4*66}[/tex]) / 2x = (17 ± 5)/2x = 11x = 6
