After solving the equation, x < -3 is the value of inequality 2-3 x<11

⇒ 2-3x < 11

⇒ -3x < 11 - 2

⇒ -3x < 9

⇒ x < -9/3

⇒ x < -3

<h3>How to solve an equation?</h3>

To solve linear equations, utilize the steps that are provided below.

  1. Remove parentheses from each side of the equation and combine similar terms to make it simpler.
  2. To separate the variable term on one side of the equation, use addition or subtraction.
  3. To find the variable, use division or multiplication.
  4. The common denominator can be multiplied by each side of the equation to eliminate fractions.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

Una compañía sabe que si produce "x" unidades mensuales su utilidad "u" se podría calcular con la expresión:
belka [17]

Answer:

Δf(u) /Δx  = 92,8    ( razón de cambio promedio)

Step-by-step explanation:

La expresión de la utilidad de la empresa u(x) en función de la cantidad de unidades producidas "x" es:

u(x) = 0,04*x² + 44*x  -4000

Entonces la razón de cambio promedio en un intervalo (a ; b)  en este caso ( 620 ;  600 ) viene dada por la expresión:

Δf(x)/ Δx  =  [ f(b)  -  f(a) ]/( b - a )

en donde  f(b)  y f(a) se obtienen por sustitución de los valores a y b es decir  600 y 620 respectivamente en la función f(x) = u(x) entonces

Δf(u) /Δx  =  [ u(b)  -  u(a) ]/( b -a )        (1)

u(b) =  0,04*(620)² + 44*(620) - 4000

u(b) = 15376 + 27280 -4000

u(b) = 2656 unidades

u(a)  = 0,04* (600)²  +  44* 600  - 4000

u(a)  = 14400  +  26400  - 4000

u(a) = 800

Sustituyendo esos valores en la ecuación 1

Δf(u) /Δx  =  2656 - 800 / 620 - 600

Δf(u) /Δx  = 92,8

The cost and revenue functions for producing and selling x units of a product are given. Cost and revenue are expressed in dolla
KIM [24]

Answer:

Step-by-step explanation:

The cost function is expressed in dollars as

C(x) = 14980 + 20x

The revenue function is expressed in dollars as

R(x) = 30x

a) At the point of break even, the total cost equals the total revenue. There is neither profit nor loss. Therefore, the the number of units that must be produced and sold to break even would be

14980 + 20x = 30x

30x - 20x = 14980

10x = 14980

x = 1498

1498 mist be produced and sold to break even.

At this level, the dollar amount coming in and going out is

30 × 1498 = $44940

b) Profit = Revenue - cost

P(x) = R(x) - C(x)

P(x) = 30x - (14980 + 20x)

P(x) = 30x - 14980 - 20x

P(x) = 10x - 14980
