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]

32*27*100,000
Answer:
There are 86400000 bacteria in the Petri dish.
Step-by-step explanation:
Write in standard form:
[tex]2^{5}[/tex] = 2 x 2 x 2 x 2 x 2 = 32
[tex]3^{3}[/tex] = 3 x 3 x 3 = 27
[tex]10^{5}[/tex] = 10 x 10 x 10 x 10 x 10 = 100000
32 x 27 x 100000
= 86400000

Examine this set of ordered pairs. (2,5) (8,9) (11,6) (18,2) (7,9) Is the set of ordered pairs a function? Choose the answer that's entirely correct.
(A) The set of ordered pairs is a function, because each input has exactly one output.
(B) The set of ordered pairs is not a function, because the output 9 has two different input values.
(C)The set of ordered pairs is a function, because each output has exactly one input.
(D) The set of ordered pairs is not a function, because the number 2 is both an input and an output.
Answer: A
Step-by-step explanation:
as long as the x-coordinates are all different numbers then it is a function.

3.(4,1) and (5,1)
4.(7,-1) and (7,5)
5.(-2,1) and (3,6)
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
What is the equation of variation if p varies jointly as q and r, and the constant of variation is 4?
a. p = 4qr
b. q = 4pr
c. 4 = pqr
d. r = 4pq
Answer:
a
Step-by-step explanation:
Given p varies jointly as q and r then the equation relating them is
p = kqr ← k is the constant of variation
Given k = 4 , then
p = 4qr ← equation of variation
write the equation of the line perpendicular to y=2/5x+7/5 that passes through the point (-4,3)
Answer: y=-5/2x+9/2
Step-by-step explanation: We are using (-4,3) as our x and y and -5/2(reciprocal of 2/5) as our slope.
y-3=-5/2(x+4)
multiply x and 4 by -5/2
y-3=-5/2x+3/2
add 3 to both sides
y=-5/2x+9/2

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

Write the equation of the line with a slope of 3/4 that passes through the point (4,-2)
Step-by-step explanation:
Slope = 3/4
Point = (4,-2)
Using the point Slope form ,
=> x - 4 = 3/4 ( y -(-2))
=> x -4 = 3/4 ( y -2)
=> 4x -16 = 3y -6
=> 4x -3y -16+6=0
=> 4x -3y -10 = 0

the answer gzzydyyxggxggxxghyzyxycycgcycyc
Step-by-step explanation:
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 :
-8x + 4z = 28
-2x - 4z = 22
--------------------
-10x + 0 = 50
x = -5
-2x - 4z = 22
-2×-5 - 4z = 22
10 - 4z = 22
-4z = 12
z = -3
y = x + z + 12
y = -5 - 3 + 12 = 4
Hannah was asked to make d the subject of the formula
d-7=4d+3/e
Finish her question.
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, .
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]
