Question

the replacement set = - 9 -, 6 ,- 3, 0 ,3, 6, 9, 12 then the solution set of 3x +7 < 1 =
​

Answer 1

Step-by-step explanation:

the replacement set = - 9 -, 6 ,- 3, 0 ,3, 6, 9, 12 then the solution set of 3x +7 < 1 =

Answer 2

Answer:

Replacement set ={−6,−3,0,3,6,9}

(1)

Truth set of the inequation are the numbers chosen from the Replacement set, that satisfies the inequation.

2x−1>9

2x>10

x>

2

10

x>5

So, the solution set ={6,9}

(2)

3x+7≤1

3x≤1−7

3x≤−6

x≤

3

−6

x≤−2

So, the solution set ={−6,−3}
