Overview: 2 questions will be solved this time.Among them
☆2 inequalities
[ 1/2Inequality]
Assignment:Find the solution set of inequality 14r+20 <14r+16 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
14 * r + 20 <14 * r + 16 (1)
From inequality(1)：
The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
The final solution set is :
The solution set is empty,that is, the inequality will never be estatlished within the real number range.
[ 2/2Inequality]
Assignment:Find the solution set of inequality 8-10r >= 15-9r .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
8 - 10 * r >= 15 - 9 * r (1)
From inequality(1)：
r ≤ -7
The final solution set is :
r ≤ -7
