Textbook Problem

In Exercises 18 to 28, first solve each inequality. Then draw a number line graph of the solutions. x 2 + 4 x ≤ x ( x − 5 ) − 18

To determine

To solve:

The following ineqaulity and draw the number line,

x2+4xx(x5)18

Explanation

Consider the following inequality,

x2+4xx(x5)18

Use distributive property on the right of the given inequality to get the following,

x2+4xx(x5)18x2+4xx25x18. Since a(bc)=abac

Then subtract by x2 on both sides to get the following,

x2+4xx2x25x18x24
