Suppose a medium pizza at Vincent’s costs $6.75 plus $0.75 for each topping, and the cost of a medium pizza at Original Italian
lapo4ka [179]

Answer:

12 toppings

Step-by-step explanation:

There's a 60 cent difference in the base price, and the price of toppings is a 5 cent difference, so it would take 60/5 or 12 toppings to make up the difference.   r, you can make a chart.  Or you can do algebra and solve an equation:

6.75 + .75 x = 6.15 + .8x  where x is the number of toppings.  Subtract 6.15 from both sides.

.60 + .75x = .8 x     Subtract .75x from both sides

.60 = .05x         Divide both sides by .05

Harper simplemente encendió una vela nueva y luego la dejó arder hasta la nada. La longitud de la vela que permanece sin quemar,
Fudgin [204]

Answer:

La pendiente de la ecuación es -1.5 y su interpretación en el contexto del problema es que en este caso este valor indica que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.

Step-by-step explanation:

La función lineal se define por la ecuación

f(x) = mx + b

o

y = mx + b

donde m es la pendiente de la recta y b es la ordenada al origen.

La gráfica de una función lineal es siempre una recta.

Como se mencionó, la m es la pendiente de la recta. La pendiente es la inclinación con respecto al eje x, que es el eje de abscisas.

La pendiente m significa que si aumentamos la x en una unidad, la y aumenta en m unidades. Si m es positiva (m > 0), entonces la función es creciente. En cambio, si la m es negativa (m < 0), entonces la función es decreciente.

En este caso, siendo L=1.5 - 1.5t y comparando con la expresión y=mx + b, podes observar que el valor de la pendiente m es -1.5. Como m es un número negativo, entonces se trata de una función decreciente. En este caso este valor de pendiente indica entonces que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.

<u><em>La pendiente de la ecuación es -1.5 y su interpretación en el contexto del problema es que en este caso este valor indica que la longitud L de la vela luego de t horas desde que se encendió la decrece en 1.5 unidades por cada hora.</em></u>
