Break-even point is that level of production at which a business unit makes no profit and no loss. The level of production and sales at which the income covers all variable and fixed costs of the business is termed the break-even point.

Divide total costs (Here 1000) by the selling price (5) to determine how many units must be sold to break even. Hence 1000/5=200.

If you only sell 199, you are losing money and have not achieved break even.

x^2+13x+15=0

Recall (x+a)^2=x^2+2ax+a^2

Write x^2+2*(13/2)x+15, and compare the terms in x.**a=13/2**

x^2+13x+15=x^2+2(13/2)x**+(13/2)^2-(13/2)^2**+15

The first three terms are the expansion of** (x+13/2)^2**

You expression is equivalent to

(x+13/2)^2-[(13/2)^2-15]=(x+13/2)^2-[SQRT(109)/2]^2

Use the identity for the difference of two squares a^2-b^2=(a-b)(a+b)

This gives

x^2+13x+15=(x+13/2)^2-[SQRT(109)/2]^2=

**[x+13/2 -SQRT(109)/2][x+13/2+SQRT(109)/2]**

The polynomial can be written as (x-a)(x-b) (Note a has nothing to do with the one used above to complete the square. You can use any name for the roots, x_1, x_2, anything.

The two roots are on the screen captures below.

PS. I prefer to manipulate exact expressions with radicals. If you do not like it use the decimal approximations.

Use the quadratic formula or completing the square.

Completing the square:

x^2 -13x=-36

x^2-2*(13/2) +(13/2)^2=-36+(13/2)^2

The left side can be factored as (x-13/2)^2.

The right side is (13^2-36*4)/4=(169-144)/4=25/4

Assembling the two sides

(x-13/2)^2=25/4

Taking the square roots x-13/2=+ or - 5/2

Case 1 : x-13/2=+ 5/2.

Solving for x you get the first root as x=(5+13)/2=18/2=9

Case 2 : x-13/2=-5/2.

Solving for x, you get the other root as x=(13-5)/2=8/2=4.

The roots are x1=9, and x2=4

Set C = R

This means 16X - 20000 = 14X

Add -16X to both sides

-20000 = -2X

Divide both sides by -2

10000 = X

This means that the break even point is 10000 units.

This means 16X - 20000 = 14X

Add -16X to both sides

-20000 = -2X

Divide both sides by -2

10000 = X

This means that the break even point is 10000 units.

Hi. try accessing the Start-up BIOS features by pressing F2 or Delete key when you see the Toshiba logo. Check for the Tab that will give you the control for the brightness/contrast of the screen. If that doesn't do anything then most probably the backlight (LED or CFL) must have been busted. and needs replacement.

[3(x-5)-4(-3x+2)]-[4(6-x)]

[(3x-15)-(12x+8)]-(24-4x)

(-9x-23)-(24-4x)

-13x-(-1)

this is 9th grade stuff.

[(3x-15)-(12x+8)]-(24-4x)

(-9x-23)-(24-4x)

-13x-(-1)

this is 9th grade stuff.

same here, you just have to keep messin' with (pluging it into computer, etc.). I know it sounds strange but that's how I deal w/mine. It eventually comes back to life.
