Answer to Problem 48PPS

The solution of the inequality is (−∞,−2) or x<−2 .

Explanation of Solution

Given:

  3x+7>4x+9

Concept Used:

  • To graph the endpoint with strict inequality < or>, use the dashed line at that endpoint.
  • To graph the endpoint with inequality symbol ≤ or≥, use the solid line at that endpoint.
  • Properties of inequality:
  1. b≤c⇒ab≤ac, if a≥0
  2. b≤c⇒ab≥ac, if a≤0

Calculation:

To solve the inequality:

  3x+7>4x+9

Now, rewrite the inequality as:

  3x+7>4x+93x+7−4x+9>0−x+2>0

Solve the inequality by using the graph of − x + 2 = 0, draw the graph of the line − x + 2 = 0 and the plane divided into two parts.

Then, chose the origin point (0, 0) and put the point into the inequality to show weather it satisfied the inequality of not.

  At (0,0):   −x+2>0−(0)+2>0    {Not satisfied}

The point (0, 0) is not in the solution set. So, the other plane is the solution set and the point that contains on the line are not the part of the solution set. Thus, it is shown as a dashed line.

By using the Desmos graphical calculator, graph the following function as:

Hence, by the graph the solution set of the inequality is given as (−∞,−2) or x<−2 .
