Answer:

  a) x = (√5 -1)/2 ≈ 0.618034

  b) 1/x = (√5 +1)/2 ≈ 1.618034

Step-by-step explanation:

Given:

  x/(1 -x) = 1/x

Find:

  Exactly, and as a decimal approximation, ...

  a) x, using the quadratic formula

  b) 1/x

Solution:

a) We can multiply the given equation by x(1 -x) to obtain ...

  x² = 1 -x

  x² +x -1 = 0 . . . . . . add x-1

The coefficients for use in the quadratic formula are a=1, b=1, c=-1. The solution using the quadratic formula is ...

  [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-1\pm\sqrt{1^2-4\cdot1\cdot(-1)}}{2\cdot1}=\dfrac{-1\pm\sqrt{5}}{2}[/tex]

We are only interested in the positive solution, which is ...

  [tex]\boxed{x=\dfrac{\sqrt{5}-1}{2}\approx0.618034}[/tex]

__

b) The quadratic we developed in the first part can be rearranged like this:

  x² +x = 1 . . . . . . add 1 to both sides

  x(x +1) = 1 . . . . . factor out x

  x +1 = 1/x . . . . . .divide by x

Then to find the value of 1/x, we simply need to add 1 to the value of x we have:

  [tex]\dfrac{1}{x}=\dfrac{\sqrt{5}-1}{2}+1=\dfrac{\sqrt{5}-1}{2}+\dfrac{2}{2}=\dfrac{\sqrt{5}-1+2}{2}\\\\\boxed{\dfrac{1}{x}=\dfrac{\sqrt{5}+1}{2}\approx1.618034}[/tex]

Sorry, but I'm not seeing the question to solve.

Did you mean to attach any pictures?

Answer:

x = 0 —> y = 0 —> ( 0 , 0 )

x = 1 —> y = – 2 —> ( 1 , – 2 )

x = 5 —> y = – 10 —> ( 5 , – 10 )

x = -3 —> y = 6 —> ( -3 , 6 )

Step-by-step explanation:

x = 0 —> y = -2x = -2(0)=0

x = 1 —> y= -2x = -2(1) = -2

x = 5 —> y = -2x = -2(5) = -10

x = -3 —> y = -2x = -2(-3) = 6

3000

Step-by-step explanation:

when you multiply by a ten (10, 100, 1000, etc.), just add a zero for each zero. it's the same when you divide: for every zero in the ten, you remove a zero.

Answer:

3000

Step-by-step explanation:

All you have to do is add one zero which is very simple so add a zero and you get your answer

Answer:

(-9,-6) ,(-3,0),(-2,1),(4,7)(6,9)

Answer:

x = -9 —> f(x) = – 6

x = -3 —> f(x) = 0

x = -2 —> f(x) = 1

x = 4 —> f(x) = 7

x = 6 —> f(x) = 9

Step-by-step explanation:

x = -9 —> f(x)= x+3 —> f(-9)= -9+3 = -6 —> f(x) = – 6

x = -3 —> f(x)= x+3 —> f(-3)= -3+3 = 0 —> f(x) = 0

x = -2 —> f(x)= x+3 —> f(-2)= -2+3 = 1 —> f(x) = 1

x = 4 —> f(x)= x+3 —> f(4)= 4+3 = 7 —> f(x) = 7

x = 6 —> f(x)= x+3 —> f(6)= 6+3 = 9 —> f(x) = 9

Answer:

  see attached.

Step-by-step explanation:

Your graph demonstrates a possible function, but it has the domain and range swapped.

__

The domain is the horizontal extent, so your line must end at x=-9 on the left and x=6 on the right.

The range is the vertical extent, so the function must extend from -4 at the bottom to +8 at the top.

The attachment shows a linear function with those characteristics.

The burnt out bulb is located between two points in the circuit that have a

discontinuity.

Reasons:

The process and steps to determine the lamp that has burned out;

The given arrangement of the bubs = Series arrangement

Therefore;

A burn out of a bulb, causes a discontinuity by opening the circuit and to current flow.

The meter to use is that determine the defective lamp is one that checks for discontinuity, or an open circuit, which is the presence of infinite resistance, which requires a resistance meter;

Therefore, the ohmmeter (resistance meter) is the best meter to use

Thanks!!!!

Answer:

y=(-3/5)x

Step-by-step explanation:

5x-3y=20

-3y=-5x+20

y=(5/3)x-(20/3)

perpendicular lines have opposite reciprocal slopes

Answer:

Perpendicular line is y = -3/5 x - 20/3

Step-by-step explanation:

First subtract 5x to move it to the other side. Now you have -3y = -5x + 20 . Next divide -3 on both sides to get y by its self. Now you have

y = 5/3 x - 20/3.

To find the perpendicular line, just remember that slope will be opposite. Look at the graph, I did for you above.⤴⤴⤴

Hope this helped :)

Step-by-step explanation:

0,06x + 0,1(20000-x) = 0,09(20000)

0,06x + 2000 - 0,1x = 1800

-0,04x = -200

x = -200 /(-0,04)

x = 5000
