What would you need to help you with it comes to solving equations?
When solving equations remember that whatever operations are performed on the LHS of the equation must be performed on its RHS to keep the equation in balance.
What is some advice for solving systems of equations?
Always keep the equation in balance inasmuch that what is done on the RHS must be done on the LHS of the equation.
Why must the rules for the order of operations be understood before solving the equations in this section?
The answer will not be the same if you do not follow the order of operations. PEMDAS is the way most people remember it. It tells you what to do first and you need to know this to do the problems correctly. If not, you will often have the wrong answer.
What is one important difference between solving equations and solving inequalities?
One important difference between solving equations and solving inequalities is that when you multiply or divide by a negative number, then the direction of the inequality must be reversed, i.e. "less than" becomes "greater than", and "less than or equal to" becomes "greater than or equal to".Actually, from a purist's sense, the reversal rule also applies with equations. Its just that the reversal of "equals" is still "equals". The same goes for "not equal to".
Why is the period of a function important when solving a trig equation?
there can be more than 1 answer for some trig equations and you must use your knowledge of periodicity to get the answers.
When solving a rational equation what is the first step you must always take?
Get rid of the denominator.
When solving two-step equations what must be undone first?
You have to follow the order of operations which goes as follows, parentheses, then exponents, then multiplication, then division, then addition, and finally subtraction
Explain how solving inequalities is alike and different from solving equations?
Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").
How do you know what operations to use when solving equations?
The simple rule to follow is that whatever is done on the Left Hand Side of the equation must be repeated on the Right Hand Side of the equation to keep it in 'balance'
What is a disadvantage of a equation?
Nothing, you must realize that almost everything is an equation. What to eat today? x = what to eat That's a bad example, but you see my point. Equations are simply a line with an equal sign. 3x + 5 = y etc. In solving any problem with an unknown using known, we must establish a relationship, and we NEED equations (or inequalities)
How do you solve the inequality2x -10 6?
This isn't an inequality, since there is no less-than, greater-than, less-than-or-equal, or greater-than-or-equal sign. However, solving inequalities is similar to solving equations; however, when you multiply by a negative number, you must change the direction of the inequality sign.
Why must you remember your war heroes?
they will always remind us to be loyal to our own country.
