Explanation of Solution
The final expression obtained of the inequality in part (a) is,
The final expression obtained of the inequality in part (b) is,
The inequality in part (a) and in part (b) is true when the value of variablechangesfrom
(d)
The method of solving the inequality among part (a) and part (b)is to be selected.
(d)
Answer to Problem 49PPE
The method of solving the inequality in part (b) is selected.
Explanation of Solution
The inequality is solved by gathering the variable terms on the left side and the constant terms on the right side in part (a) while the inequality in part (b) is solved by gathering the constant terms on the left side and the variables terms on the right side.
The sign of inequality in part (a) is to be changed to make the whole expression positive while the solution of inequality is positive in part (b). The expression of inequality is positive without making any change in the sign. Therefore, the method of solving the inequality in part (b) is selected.
