Question

The sun of D and 5 is greater than or equal to -1 and the sun of D and 5 is less than or equal to 4. List 3 integers that satisfy the inequality

Answer 1

-5, -2, -1

Explanation:

Inequalities

The question provides us with two conditions:

D+5≥-1

D+5≤4

Solve the first inequality. Subtract 5 to both terms:

D≥-1-5

D≥-6

Solve the second inequality. Subtract 5 to both terms:

D≤4-5

D≤-1

We must find three numbers that comply with both conditions, i.e. it must be greater or equal -6 and less or equal than -1. Any integer number in the interval [-6,-1] solves the problem. We select the following list:

-5, -2, -1
