Express v in terms of w

Express V In Terms Of W

Answers

Answer 1

Answer:

[tex]v=\frac{2w}{2w-1}[/tex]

Step-by-step explanation:

[tex]w = \frac{v(1-w)}{v-2}[/tex]

Multiply both sides by (v - 2) to remove the fraction

[tex]w(v-2) = v(1-w)[/tex]

Expand both sides

[tex]vw-2w=v-vw[/tex]

Add 2w to both sides (to make the left side simpler)

[tex]vw = v - vw + 2w[/tex]

Subtract (v - vw) from both sides

[tex]vw - (v - vw)=v-vw+2w-(v-vw)[/tex]

Simplify

[tex]2vw - v=2w[/tex]

Factor 2vw - v

[tex]v(2w-1) = 2w[/tex]

Divide both sides by (2w - 1)

[tex]\frac{v\left(2w-1\right)}{2w-1} = \frac{2w}{2w-1}[/tex]

Simplify

[tex]v=\frac{2w}{2w-1}[/tex]

Rewrite the following in ascending order.
(a) -3/8, 5/-12, -7/16, -13/18, 11/-24​

Answers

Answer:

-13/8 , -11/24, -7/16, -5/12 , -3/8

Step-by-step explanation:

Given numbers are -3/8 , 5/-12, -7/16, -13/18 , 11/-24

The can be written as -3/8, -5/12, -7/16, -13/18, -11/24

The denominators = 8,12,16,18,24

LCM of the denominators = 144

-3/8 = (-3/8)×(18/18) = -54/144

-5/12 = (-5/12)×(12/12) =-60/144

-7/16 = (-7/16)×(9/9) = -63/144

-13/18 = (-13/18)×(8/8) = -104/144

-11/24 = (-11/24)×(6/6) = -66/144

Ascending order of the numbers

= -104/144 , -66/144, -63/144, -60/144, -54/144

-13/8 , -11/24, -7/16, -5/12 , -3/8

Answers

Step-by-step explanation:

Number 1

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

m = (3 - 1)/(5 - 2)

m = 2/3 POSITIVE

Number 2

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

m = (-3 - 1)/(1 + 2)

m = -4/3 NEGATIVE

Number 3

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

m = (1 - 1)/(5 - 4)

m = 0/1

m = 0 ZERO

Number 4

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

m = (5 - 1)/(7 - 7)

m = 4/0

m = UNDEFINED

Number 5

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

m = (6 - 1)/(3 + 2)

m = 5/5

m = 1 POSITIVE

Hannah was asked to make d the subject of the formula
d-7=4d+3/e
Finish her question.

Answers

Answer:

[tex]d = \frac{-1}{e} - \frac{7}{3}[/tex]

Step-by-step explanation:

In order to make d the subject of the formula, you need to isolate it.

- You started with d-7 = 4d + 3/e

- Move 4d to the left side by subtracting 4d from both sides to cancel it from the right so you have...

d - 7 = 4d + 3/e              This will leave you left with -3d - 7 = 3/e

-4d     -4d                          

- Then move over the -7 by adding 7 to both sides...

-3d - 7 = 3/e              This will leave you left with -3d = 3/e + 7

     +7          +7

- Finally to get d by itself divide both sides of the equation by -3 and you'll be left with...

[tex]d = \frac{3}{-3e} -\frac{7}{3}[/tex]

- You can cancel out the 3 in the -3/3e and make it -1/e so your final answer will be

[tex]d = \frac{-1}{e} - \frac{7}{3}[/tex]

Drag each tile to the correct box. Complete the sequence for deriving the quadratic formula using the quadratic equation in standard form, .

Answers

Answer:

see the picture

Step-by-step explanation:

By the below figure (6) is the initial equation

(1) next added (b/2a)^2 on both sides to make it whole square on left side which gives (4) in (4) both terms are added on the right side to make it (5)

then square root on both sides gives (2) and now taking b/2a to the right side gives the final quadratic formula (3)

We can obtain the quadratic formula from completing the square method as shown.

The quadratic formula is derived from the completing the square method as follows;

Given the quadratic equation;

[tex]ax^{2} + bx + c =0[/tex]

Dividing through by a we have;

[tex]x^{2} + \frac{b}{a} + \frac{c}{a} = 0[/tex]

Adding half of b to both sides of the equation, we have;

[tex](x + \frac{b}{a}) ^{2} = \frac{-c}{a} + \frac{b^2}{4a^2}[/tex]

Taking LCM of the right hand side;

[tex](x + \frac{b}{2a})^{2} = \frac{b^2 - 4ac}{4a^2}[/tex]

Making x the subject of the formula;

[tex]x = \frac{-b + \sqrt{b^2 - 4ac} }{2a}[/tex]

we start with the first and the third equations, as they have the same content structure.

we multiply the whole first equation by 2, so that the z terms become aligned, and then we add both equations :

-2x - 4z = 22

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

-10x + 0 = 50

x = -5

-2x - 4z = 22

-2×-5 - 4z = 22

10 - 4z = 22

-4z = 12
