Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 &gt; 0
AnnyKZ [126]

we have

x^{2}+2x + 1 > 0

we know that

x^{2}+2x+1=(x+1)^{2}

so

(x+1)^{2}> 0

two solutions

<u>first solution </u>

(x+1)> 0

x > -1

the first solution is the interval---------> (-1,∞)

<u>second solution</u>

-(x+1)> 0

-x-1> 0

-x> 1

x< -1

the second solution is the interval---------> (-∞,-1)

therefore

the solution is all real numbers except the number -1

Answer:

La cantidad de dinero adeuda al final de los dos procesos es $1450

Step-by-step explanation:

Los parámetros del proceso son;

La cantidad ahorrada para comprar ropa = $2,000

La cantidad pagada por la ropa = $2600

La cantidad prestada a un amigo = $650

La cantidad adeuda por teléfono celular durante 3 meses = $250

Deje que 'C', represente la suma de las transacciones anteriores, tenemos;

∴ C = 2,000 - 2,600 - 650 - 200 = -1,450

La suma de las transacciones anteriores, C = -$1,450

Por lo tanto, al final de los dos procesos, la cantidad de dinero adeuda es C = $1,450
