How do you know if a specific point is a solution to an inequality?
substitute the numbers into the inequality and see if it is true. EX: x > y+ 3 for the point (1, 6) .... 1 > 6 + 3 is not true so this point is not a solution.
Is 2 a solution to the inequality x 3?
Yes, It is a solution (a+)
Is the solution to a quadratic inequality in one variable always a compound inequality?
Yes - except in extreme cases. It can be the whole of the Real Numbers: eg x2 > -3 It can be a single point eg x2 ≤ 0 gives x = 0
How does solving linear inequality differ from solving linear equation?
Linear inequalities are equations, but instead of an equal sign, it has either a greater than, greater than or equal to, less than, or a less than or equal to sign. Both can be graphed. Solving linear equations mainly differs from solving linear inequalities in the form of the solution. 1. Linear equation. For each linear equation in x, there is only one value of x (solution) that makes the equation true. The equation: x - 3 = 7 has one solution, that is x = 10. The equation: 3x + 4 = 13 has one solution that is x = 3. 2. Linear inequality. On the contrary, a linear inequality has an infinity of solutions, meaning there is an infinity of value of x that make the inequality true. All these x values constitute the "solution set" of the inequality. The answers of a linear inequality are expressed in the form of intervals. The linear inequality x + 5 < 9 has as solution: x < 4. The solution set of this inequality is the interval (-infinity, 4) The inequality 4x - 3 > 5 has as solution x > 2. The solution set is the interval (2, +infinity). The intervals can be open, closed, and half closed. The open interval (1, 4) ; the 2 endpoints 1 and 4 are not included in the solution set. The closed interval [-2, 5] ; the 2 end points -2 and 5 are included. The half-closed interval [3, +infinity) ; the end point 3 is included.

Solve the inequality and enter your solution as an inequality comparing the variable to the solution -3 plus x10?
Solve the inequality and enter your solution as an inequality comparing the variable to the solution. -33+x<-33
Which is NOT a solution of the inequality 5-2x -3?
Blue is not a solution.
Is 2 a solution to the inequality x 3?
Yes, It is a solution (a+)
Is 2 a solution of the inequality 2x 5 9?
2 is a solution of the equation, but not if it's an inequality.
Is 4 a solution of the inequality x 3?
Yes
Is 3 a solution to the inequality x 3?
No, it is not a solution.
What is a solution of y - x -3?
y - x - 3 is an expression, not an equation nor an inequality. It cannot, therefore, have a solution.
