Let's solve the inequality. The product of three and the binomial three minus X is greater than or equal to six plus X. Let's start by rewriting the inequality without the parentheses. To do this, we need to distribute three into the binomial on the left side. Three times three is nine three times negative X minus three x nine minus three X is greater than or equal to six plus x. Let's isolate the variable to the left side of the inequality by subtracting X from both sides. Nine. Minus four X is greater than or equal to six. Next, we're going to subtract nine from both sides. Toe. Isolate the negative for X negative. Four X is greater than or equal to negative three. And the final step here is to isolate X by using the inverse property of multiplication and divide both sides of inequality. My negative four. Because we're dividing by a negative, we need to remember to flip the inequality symbol this leaves us with X is less than or equal to positive. 3/4 an interval notation. We're going to open the interval with a parentheses at negative Infinity enclose the interval with a bracket at 3/4. Remember, the bracket is to indicate that the value of 3/4 is included in the solution set on our number line. Start with a closed circle at 3/4 and shade all values that are less than or equal. So we're going to shade to the left on our number line to include all values less than or equal to 3/4.
