standard_description: Graph the solutions to a linear inequality in two variables as a half plane (excluding the boundary in the case of a strict inequality), and graph the solution set to a system of linear inequalities in two variables as the intersection of the corresponding half-planes.
problem_activity: Problem 1
Part A:
Describe the solution set to the inequality “
$$x$$
is greater than
$${-4}$$
and less than
$$5$$
” algebraically and graphically.
Part B:
Graph the solution set to the compound inequality shown below.
$$-5<2x+ 1<4$$
Problem 2
Jonah got a 76 on his midterm exam. To get a B in the course, the average of his midterm and his final must be between 80 and 89.
Write and solve a compound inequality that models this context. Describe the solution set in context of the problem.
