To solve and graph: the given inequality
Answer to Problem 23CR
Explanation of Solution
Given:
Calculation:
Equation 1:
Multiply both sides by -5
r<
Simplify
Equation 2:
Add both sided by 7
Divide both side by -2
Reverse the inequality symbol
Since the inequalities are joined by "or", take the union of the inequalities as its solution set.
Therefore, its graph should have an open point at 25 and a shaded line going to the left and a closed point at -5 and a shaded ling going to the right of
Conclusion:
Therefore, its graph should have an open point at 25 and a shaded line going to the left and a closed point at -5 and a shaded ling going to the right of
