The opposite of any positive number is the negative version and the opposite of any negative number is the positive version so the opposite of 7 is -7

Answer: -7

Step-by-step explanation: Here we're asked to determine the opposite of the following integer which is 7.

Think of the opposite of an integer in terms of a number line. The opposite of an integer is the same distance from zero as the original integer but on the opposite side of 0.

Since 7 is 7 units to the right of 0,

its opposite will be 7 units to the left of 0.

So the opposite of 7 is -7.

zhannawk [14.2K]
Ok
1/9=1present
3hours=xpresent

1/9 times x=3
multiplyboth sides by 9
x=27
answer is 27

another way is
1/9 hour=1 present
1hour=9present
3 hour=27 present

Determine en donde la funcion dada es creciente,concava hacia riba y concava hacia abajo. y= x3–3x–1
Minchanka [31]

Answer:

Es creciente en los siguientes intervalos: [-\infty,-1] U [1,\infty]

Es concavo hacia abajo en el intervalo: [-\infty,0)

Es concavo hacia arriba en el intervalo: (0,\infty]

Step-by-step explanation:

Sea la función:

f(x)=x^{3}-3x-1

Para determinar el intervalo de crecimeinto debes determinar la primer derivada de la función (f'(x)). El intervalo donde f'(x) > 0 es creciente.

La derivada de f(x) es:

f'(x)=3x^{2}-3

Entonces es creciente en los siguientes intervalos:

[-\infty,-1] U [1,\infty]    

Ahora para determinar la concavidad debemos determinar la segunda derivada de la función (f''(x)). Si f''(x) > 0 la función es concava hacia arriba, si f''(x) < 0 la funcion es concava hacia abajo.

La segunda derivada de f(x) es:

f''(x)=6x        

Por lo tanto:

Es concavo hacia abajo en el intervalo: [-\infty,0)

Es concavo hacia arriba en el intervalo: (0,\infty]

Espero te haya ayudado!

Aniya went bowling and spent $5 to rent bowling shoes and paid $6.75 per game bowled. If Aniya spent $25.25 total, answer the fo
Mashcka [7]

Answer:

Aniya only needs to pay for her shoes once so $5 is your B or y-intercept. $6.75 is your slope. So your equation in y-intercept form will be y = $6.75x + $5. Now plug in the numbers to find how many games she played if she spent $25.25.

Equation: y = $6.75x + $5

Answer for B:

($25.25 - $5) / $6.75

The answer: She played three games.

Answer for C:

y = $6.75 * 10 + $5

The answer: She paid $72.5 if she bought 10 games and rented a pair of shoes.
