Magazine Problem 69
Solve each inequality in Exercises 57-84 by first rewriting each one as an equivalent inequality without absolute value bars. Graph the solution set on a number line. Express the solution set using interval notation. $$|x-1| \geq 2$$
Problem 69
Solve each absolute value equation or indicate the equation has no solution. $$ |x+1|+5=3 $$
Problem 69
In Exercises \(69-72,\) use inspection to describe each inequality's solution set. Do not solve any of the inequalities. $$ (x-2)^{2}>0 $$
Problem 69
Compute the discriminant of each equation in Exercises 65-72 What does the discriminant indicate about the number and type of solutions? \(x^{2}-2 x+1=0\)
Problem 69
In Exercises \(57-76,\) solve each formula for the specified variable. Do you recognize the formula? If so, what does it describe? \(S=P+P r t\) for \(r\)
Problem 70
In Exercises \(69-72,\) use inspection to describe each inequality's solution set. Do not solve any of the inequalities. $$ (x-2)^{2} \leq 0 $$
Problem 70
Compute the discriminant of each equation in Exercises 65-72 What does the discriminant indicate about the number and type of solutions? \(3 x^{2}=2 x-1\)
Problem 70
Solve each absolute value equation or indicate the equation has no solution. $$ |x+1|+6=2 $$
Problem 70
