if the replacement set is the set of integers, find the solution set for the inequality:
x - 9 < -15

a){-8, -7, -6, ...}

b){-9, -8, -7,...}

c){......, -8, -7, -6}

d){....., -9, -8, -7}

Respuesta :

Answer:

c.    {....., -8, -7, -6}

Step-by-step explanation:

x - 9 < -15

x < -6

The value of x must be less than -6. From the set of values, the values less than -6 are -7, -8, -9.... The correct sets is {......,-8, -7, -6}

Given the inequality expression

x - 9 < -15

Add 9 to both sides

x - 9 + 9< -15 + 9

x + 0 < -15 + 9

x < -15 + 9

x < -6

Hence the value of x must be less than -6. From the set of values, the values less than -6 are -7, -8, -9.... The correct sets are {......,-8, -7, -6}
