Which is the best interpretation of the solution set for the compound inequality?
andriy [413]

Answer:

  all real numbers

Step-by-step explanation:

Here is the solution to the first inequality:

  3(2x +1) > 21 . . . . . . given

  6x +3 > 21 . . . . . . . . eliminate parentheses

  6x > 18 . . . . . . . . . . .subtract 3

  x > 3 . . . . . . . . . . . . divide by 6

This is all numbers to the right of 3 on the number line.

__

The solution to the second inequality is ...

  4x +3 < 3x + 7 . . . . given

  x < 4 . . . . . . . . . . . . subtract 3x+3

This is all numbers to the left of 4 on the number line.

__

The conjunction in the system of inequalities is "or", so we are looking for values of x that will satisfy at least one of the conditions. <em>Any value of x</em> will satisfy one or the other or both of these inequalities. The solution is all real numbers.
