Consequently, what does and and/or mean in compound inequalities?
Compound Inequalities. A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time. It is the overlap or intersection of the solution sets for the individual statements.
Subsequently, question is, are absolute value inequalities AND or OR? This pattern for “greater than” absolute–value inequalities always holds: Given the inequality | x | > a, the solution always starts by splitting the inequality into two pieces: x < –a or x > a. And, by the way, the correct conjunction is “or”, not “and”.
Consequently, how do you tell if a compound inequality is AND or OR?
A compound inequality contains at least two inequalities that are separated by either “and” or “or”. The graph of a compound inequality with an “and” represents the intersection of the graph of the inequalities. A number is a solution to the compound inequality if the number is a solution to both inequalities.
How do you solve and/or inequalities?
To solve a compound inequality, first separate it into two inequalities. Determine whether the answer should be a union of sets (“or”) or an intersection of sets (“and”). Then, solve both inequalities and graph.

How do you do absolute value?
- Step 1: Isolate the absolute value expression.
- Step2: Set the quantity inside the absolute value notation equal to + and – the quantity on the other side of the equation.
- Step 3: Solve for the unknown in both equations.
- Step 4: Check your answer analytically or graphically.
How do you write absolute value?
On most computer keyboards, you can find the “|” symbol above the backslash, which looks like “”. To type it, simply hold down the shift key and strike the backslash key.
How do you know if an inequality is a conjunction or disjunction?
How do you solve system of equations?
- Step 1: Solve one of the equations for one of the variables. Let’s solve the first equation for y:
- Step 2: Substitute that equation into the other equation, and solve for x.
- Step 3: Substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
How do you find the absolute value inequality?
- Isolate the absolute value expression on the left side of the inequality.
- If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions.
Who created absolute value?
What are the rules for inequalities?
- If a < b, then a + c < b + c.
- If a < b, then a – c < b – c.
- If a < b and if c is a positive number, then a · c < b · c.
- If a < b and if c is a positive number, then.
- If a < b and if c is a negative number, then a · c > b · c.
- If a < b and if c is a negative number, then.
