Question

How many positive integers are in the solution set of the inequality below? -2x + 1 ≥ -6

Answer 1

3 integers, with values: 1,2,3

Explanation:

-2x+1>=-6

2x-1<=6

2x<=7

Positive integers: x=1,2,3

Count: 3

Answer 2

3 positive integers

Explanation:

-2x + 1 ≥ -6

-2x≥-6-1

-2x≥-7

2x≥7

Divide both sides by 2

2x/2≥7/2

x≥7/2

x≥3.5

By interpretation, it reads x greater than or equal to 3.5

That's 1, 2, 3 and even 3.5

That's 3 positive integers
