![]() The next day, the temperature in Minneapolis was warmer than -9 ☏. Write an inequality which is true only for temperatures t that are warmer than -9 ☏. The next day, the temperature in Minneapolis was warmer than -9 ☏.Ī. Put a closed point on the number 5 running to the right. Write an inequality to describe the widths w that will yield a fenced-in area of at least 50 square feet. The length of the fence must be 10 feet.Ī. A farmer needs to build a fence to enclose a chicken pen with an area greater than or equal to 50 square feet. To find the area A of a rectangle, the length l must be multiplied by the width w. The shaded circle indicates the number 8 is included in the solution. The shaded circle indicates the solution includes the 500. Write and graph an inequality to show the number of flying hours h Camille needs to get a license.Ī pilot needs to log at least 500 flying hours before earning a pilot’s license. A pilot needs to log at least 500 flying hours before earning a pilot’s license. The circle indicates that the number 4 is not the solution.Ĭamille wants to become a pilot. The number 4 is not included in the solution. 5 ≤ -3 is true, the solution on the number line appears correct. 4 ≤ -3 is true, the solution on the number line appears correct. The shaded circle on the -3 indicates that -3 is a solution of x ≤ -3. So, -3 is a solution of x ≤ -3, but numbers greater than -3 are not solutions. You can never check all the possible values for the variable but checking one or two values helps assure you have shaded the correct side of the number line.įor the inequality x ≤ -3, the values of x must be less than or equal to -3. Since the inequality -4 ≤ -3 is true, the solution graphed on the number line appears to be correct. Choose a number that is on the shaded section of the number line, such as -4. Step 2: Shade the number line to the left of -3 to show that numbers less than -3 are also solutions. Step 1: Draw a solid circle at -3 to show that -3 is a solution. So, 4 is a solution of x ≤ 4, but numbers greater than 4 are not solutions. So, 2 and numbers less than 2 are not solutions of x > 2.įor the inequality x ≤ 4, the values of x must be less than or equal to 4. For the inequality x > 2, the values of x must be greater than 2. A constraint is a condition that restricts the values of a quantity or variable to a given value or range of values. An inequality can have many solutions.Īn inequality such as x > 2 represents a constraint. ![]() The solution of an Inequality is a value or values that make an inequality true. The solution of the inequality x > 2 is all numbers greater than 2, not including 2. Turn and Talk How is a number line not like a thermometer? Explain. The temperatures recorded in Texas is 4 ☏, -3 ☏, -14 ☏, 1 ☏, and -19 ☏.Ĭomparing the above temperature with -23 ☏. How do these temperatures compare to -23 ☏? ![]() The temperatures 4 ☏, -3 ☏, -14 ☏, 1 ☏, and -19 ☏ have also been recorded in Texas. Find -23 and graph it on the number line.ī. You can write inequalities using inequality symbols and variables to describe quantities that have many values.Īn Inequality is a mathematical sentence that shows the relationship between quantities that are not equal.Ī record-breaking low temperature of -23 ☏ was recorded in Seminole, Texas, on February 8, 1933.Ī. I Can write and graph the solution of an inequality to represent a condition in a real-world or mathematical problem.
