Line Q has a slope of one half and crosses the y axis at 3. Line S has a slope of one half and crosses the y axis at negative 2.
harkovskaia [24]
Line Q's equation would be y=1/2x+3 and line S's equation is Y=1/2x-2. You would compare them. So you would get 1/2x+3=1/2X-2. Subtract 1/2X from both sides and you get 3=-2. So the answer is these lines have no solution.

How do you find the average rate of change through an interval
soldier1979 [14.2K]
In order to find average rate of change over an interval, do the y2-y1/x2-x1. Solve y for x=9 and x= 4
y2 = -3(9-4)^2 + 3 = -72
y1 = -3(4-4)^2 + 3 = 3

Now, x2 matches with y2 and and x1 matches with y1 obviously...
-72 - 3/9 - 4 = -15

Una pequeña empresa dedicada a la fabricación de muebles lanzará al mercado un nuevo modelo de escritorio para escolares a un pr
Pie

Answer:

Se debe fabricar y vender 553 escritorios para lograr una utilidad de S/ 25000.

Step-by-step explanation:

La utilidad por cada escritorio se obtiene al sustraer los costes fijos y variables del precio, es decir:

u = S/ \,125 -S/\,4,75 - S/\,75

u = S/\,45.25

El número de escritorios a vender para obtener S/\,25000 se calcula mediante la siguiente regla de tres simple:

x = \frac{S/\,25000}{S/\,45,25} \times 1\,esc

x = 552.486

Puesto que la cantidad a vender es una variable entera, se debe redondear al entero más cercano. En consecuencia, se debe fabricar y vender 553 escritorios para lograr una utilidad de S/ 25000.
