We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)

Here the line passes through the point (-2 ,9)

x₀ = -2 and y₀ = 9 and Given : Slope(m) = -14

Equation of the line :

⇒ y - 9 = -14(x + 2)

3rd Option is the Answer

Una compañía suministra electricidad. Cobra $100 mensuales fijos más 15 centavos por kilowatt hora. En los primeros 400 kilowatt
sweet [91]

Answer:

La función resultante es una función a trozos:

C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}

Step-by-step explanation:

El coste total de la electricidad suministrada (C_{T}), medida en pesos, es la suma del coste fijo (C_{F}) y el coste variable (C_{V}), medidas en pesos.

C_{T} = C_{F}+C_{V} (1)

Ahora, tenemos que el coste fijo es $ 100 mensuales, así:

C_{F} = \$ \,100 (2)

Y el coste variable considera que se cobra 15 centavos por kilowatt-hora para los primeros 400 kilowatts-hora y 12 centavos por kilowatt-hora para cada kilowatt-hora que pase de 400 kilowatts-hora en el mes:

(i) Menos o igual que 400 kilowatts-hora:

C_{V} = 0.15\cdot x (3)

Donde x es la electricidad suministrada en kilowatts-hora.

(ii) Mayor que 400 kilowatts-hora:

C_{V} = 0.15\cdot (400)+0.12\cdot (x-400)

C_{V} = 12+0.12\cdot x

La función resultante es una función a trozos:

C_{T}(x) = \left\{\begin{array}{cc}100+0.15\cdot x,\,0\le x \le 400\\112+0.12\cdot x,\,x> 400\\\end{array}
