Question

Consider the inequality x + 7 < 9. Select all the true statements. A. x= 3 is not a solution to the inequality because 10 is not less than 9 B. x= 3 is a solution to the inequality because 10 is less than 9 C. x= 2 is a solution to the inequality because 9 is less than 9 D. x = 2 is not a solution to the inequality because 9 is not less than 9 E. x = 1 is a solution to the inequality because 8 is less than 9 0

Answer 1

According to the given inequality:

$\begin{gathered} x+7<9 \\ x<9-7 \\ x<2 \end{gathered}$

All solutions for x must be less than 2, it means 3 is not a solution and neither is 2. The true statements are the first, the fourth and the last ones.

The right answers are A, D and E.
