The Interpreting and solving linear inequalities exercise appears under the 7th grade (U.S.) Math Mission, Algebra basics Math Mission, Mathematics I Math Mission, Algebra I Math Mission and Mathematics II Math Mission. This exercise practice working with linear inequalities.
Types of Problems
There are three types of problems in this exercise:
- Write inequality and find correct graph: This problem provides an inequality and four number line graphs. The user is expected to find the correct inequality and indicate the graph that correctly illustrates the inequality.
- Write an initial inequality and solve: This problem has a word problem that involves an inequality. Users are is expected to write the inequality and solve the inequality.
- Write inequality and find numerical solution: This problem has an inequality in a word problem. The user is asked to write the inequality and provide a reasonable answer to the question asked.
Strategies
Confidence with word problems and an ability to translate between English and math are the greatest advantages.
- If the is isolated on the left, then the inequality as an "arrowhead" faces the direction that should be shaded.
Real-life Applications
- For most people, in order to get their license they have to be at least 16. So, they can write this as an inequality. is the age of a person who wants to drive. In this case has to be greater than or equal to 16.
- Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
