a.
How do you solve a linear inequality?
a.
Answer to Problem 20RCC
The rules are described.
Explanation of Solution
Given information:
How do you solve a linear inequality?
Calculation:
A linear inequality that consisting of constant term and multiple of the variable, we can solve the inequality by isolating the variables on one side of the inequality.
Then isolating the constant terms on the other side of the inequality .
Now divide both sides of the inequality with coefficients of variables.
The remaining inequality yields the solution to the inequality.
Hence,the rules are described.
b.
How do you solve a non-linear inequality?
b.
Answer to Problem 20RCC
The rules are described.
Explanation of Solution
Given information:
How do you solve a non-linear inequality?
Calculation:
A non linear inequality that consisting of terms that are power of variables or square roots we can solve this by isolating the variables on one side of the inequality.
First move all the terms on the one side of the inequality.
Then factorised the terms. Then solve the inequality as if there are an equlity sign, to find where each factor is equal to zero.
Finding these numbers divide the real line into intervals.
Hence,the rules are described.
