What is a system of linear inequalities?
Graph the solution set of each system of inequalities or indicate that the system has no solution.. \left\\{\begin{array}{l}3 x+y \leq 6 \\\2 x-y \leq-1 \\\x \geq-2 \\\y \leq 4\end{array}\right.
When graphing \(3 x-4 y<12,\) it's not necessary for me to graph the linear equation \(3 x-4 y=12\) because the inequality contains a \(<\) symbol, in which equality is not included.
The toll to a bridge is \(\$ 3.00 .\) A three-month pass costs \(\$ 7.50\) and reduces the toll to \(\$ 0.50 .\) A six-month pass costs \(\$ 30\) and permits crossing the bridge for no additional fee. How many crossing per three-month period does it take for the three-month pass to be the best deal?
Will help you prepare for the material covered in the next section. Find all values of \(x\) satisfying \(3 x-1=x+5\) or \(3 x-1=-(x+5)\)
