Answer:

n ≤ 4

Step-by-step explanation:

"The difference between a number and seven is less than or equal to -3" translates into n - 7 ≤ -3. To solve, isolate the variable n.

n - 7 ≤ -3

n ≤ -3 + 7

n ≤ 4

Mariulka [41]

Answer:

Para trasladar 300 cajones, las dos opciones cuestan los mismo. Son indiferentes entre si.

Step-by-step explanation:

<u>Dada la siguiente información:</u>

<u></u>

Cantidad de cajones= 300

Opción A:

Camiones con capacidad para 50 cajones que cobran 150 por viaje.

Cantidad de camiones= 300/50= 6

Opción B:

Camiones con capacidad de 60 cajones por 180 por viaje.

Cantidad de camiones= 300/60= 5

<u>Debemos calcular el costo total de cada opción y elegir la de menor costo.</u>

Costo total A= 150*6= $900

Costo total B=180*5= $900

Para trasladar 300 cajones, las dos opciones cuestan los mismo. Son indiferentes entre si.

The parabola x = y² - 9 opens: <br> a.)up <br> b.)down<br> c.) right <br> d.)left
Zolol [24]

Answer:

Right side towards positive x axis

Step-by-step explanation:

Let us see the basic rule to find the orientation of parabolas.

1.  If power if x is 2 and y is 1 , the parabola opens up or down.

2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.

3. If the coefficient of x^{2} in case 1 is negative it opens downward

4. If the coefficient of y^{2}  in case 2 is negative , it opens left towards negative x axis.

Hence our equation is

x=y^2-9

here is satisfies the case 2. hence it opens right or left . Also the coefficient of  

y^{2} is positive so it opens up to the right side , that is towards positive x axis.
