Best ResponseYou've already chosen the best response.1hi, can someone help me write this in set notation, find the solution and write it in interval notation, and how to graph it

Best ResponseYou've already chosen the best response.1sorry it's really messy

Hero

Best ResponseYou've already chosen the best response.1That's perfect. Next rewrite 1 As A fraction So that both fractions have the same denominator

Best ResponseYou've already chosen the best response.1That's a good start I suppose. But we need both fractions to have the same denominator. Remember, anything over itself Is 1 . Can you think of a way to rewrite 1 so that both fractions have the same denominator?

Best ResponseYou've already chosen the best response.1Awesome . Now you can combine the fractions but be careful. am going to help you with this next step.

heyitslizzy13

Best ResponseYou've already chosen the best response.1the denominator doesn't cancel out?

Hero

Best ResponseYou've already chosen the best response.1when you rewrite 1 as a fraction, especially When doing subtraction of algebraic expressions, you should make a habit of placing parenthesis around the egression in the numerator so that you remember to distribute the negative

Best ResponseYou've already chosen the best response.1ok so now it'sdw:1442686906249:dw

heyitslizzy13

Best ResponseYou've already chosen the best response.1that's how i learned it you don't subtract when they're the same :) ok i see what you're saying

Hero

Best ResponseYou've already chosen the best response.1perfect. Now factor the denominator.

Best ResponseYou've already chosen the best response.1Very good. Now we should make A number line and plot our critical points. Any ideas on that?

heyitslizzy13
 one year ago
Best ResponseYou've already chosen the best response.1what're critical points?

Hero
 one year ago
Best ResponseYou've already chosen the best response.1The critical points are the values On the number line that are not in the domain of the expression' They are the values that x Cannot equal

Hero

Best ResponseYou've already chosen the best response.1correct, now draw a number line that induces those points.

Best ResponseYou've already chosen the best response.1Or rather, that excludes those points. Hence open circle

Hero

Best ResponseYou've already chosen the best response.1I recommend writing the number line this way for clarity And Simplicity

Hero
 one year ago
Best ResponseYou've already chosen the best response.1The reason you want to Write it that way is because it shows three distinct intervals that we can work with.

Hero
 one year ago
Best ResponseYou've already chosen the best response.1Next we Will test convenient Values between the critical points by inserting those convenient points from each interval into the factored expression.

Hero
 one year ago
Best ResponseYou've already chosen the best response.1One easy convenient Value We can test is x=0

Hero
 one year ago
Best ResponseYou've already chosen the best response.1If it passes the test, then the interval x=0 comes from is at least one Of the solutions

heyitslizzy13
 one year ago
Best ResponseYou've already chosen the best response.1it does not pass it

Hero
 one year ago
Best ResponseYou've already chosen the best response.1Okay, if not then, We can eliminate that interval ( 2 , 3) as a possible solution

Hero
 one year ago
Best ResponseYou've already chosen the best response.1try testing one value from each of the other two Intervals.

heyitslizzy13

Best ResponseYou've already chosen the best response.11 does not work either

Hero
 one year ago
Best ResponseYou've already chosen the best response.11 is from the interval ( 2 , 3)

Hero
 one year ago
Best ResponseYou've already chosen the best response.1We already eliminated that Interval

heyitslizzy13

Best ResponseYou've already chosen the best response.1wait but 1 worked

Hero
 one year ago
Best ResponseYou've already chosen the best response.1Okay sorry, We need to line modify our number line because 1 is also a critical point.

heyitslizzy13

Best ResponseYou've already chosen the best response.1the circle is shaded in for 1 right?

Hero
 one year ago
Best ResponseYou've already chosen the best response.1So We have 4 intervals now that We need to test. Pick values from each.

Hero

Best ResponseYou've already chosen the best response.1Let me know what works and What doesn't

Hero
 one year ago
Best ResponseYou've already chosen the best response.1I agree the 2 And3 Works. Anything else?

Hero
 one year ago
Best ResponseYou've already chosen the best response.13 and 4 are from the sand Interval. pµc values from the Other two intervals you haven't checked yet

heyitslizzy13
 one year ago
Best ResponseYou've already chosen the best response.1I've tried from all intervals now

Hero

Best ResponseYou've already chosen the best response.1So what is the solution for the original inequality?

heyitslizzy13

Best ResponseYou've already chosen the best response.1in interval notation it'd be

Best ResponseYou've already chosen the best response.1thank you!! can you tell me the difference between set notation and interval notation?

Hero

Best ResponseYou've already chosen the best response.1Here's a good tutorial that explains well enough: http://www.regentsprep.org/regents/math/algebra/ap1/intervalnot.htm

heyitslizzy13

Best ResponseYou've already chosen the best response.1i understand the interval notation but the set notation throws me off, how could i write it

Hero
 one year ago
Best ResponseYou've already chosen the best response.1i. We use curly brackets for set notation. ii The vertical bar separates two descriptive Components The Componentt to the left of the bar identifies the variable and the number line used. In this case, the variable is x And the number line represents all real numbers. The component to the right't the vertical bar simply identities ' the Solution interval

heyitslizzy13
 one year ago
Best ResponseYou've already chosen the best response.1what're descriptive components

heyitslizzy13
 one year ago
Best ResponseYou've already chosen the best response.1okay so in this case i want to represent the number line right

Hero
 one year ago
Best ResponseYou've already chosen the best response.1The descriptive components of a set are simply mathematical statements or expressions used to identify things like the variable, the number line and the interval Of interest. These things just simply tell you how to reconstruct the number line

Best ResponseYou've already chosen the best response.1Well, not exactly. First you hare to rewrite each Interval notation as an inequality.

heyitslizzy13
 one year ago
Best ResponseYou've already chosen the best response.1how could i do that

Hero
 one year ago
Best ResponseYou've already chosen the best response.1For example ( a,b) means the same as a<x<b

Best ResponseYou've already chosen the best response.1That's almost perfect but we don't know what Kind of set x IS.

heyitslizzy13

Best ResponseYou've already chosen the best response.1mm what do you mean?

Hero
 one year ago
Best ResponseYou've already chosen the best response.1X belongs to what kind of Set? Integers?, natural numbers? Real Numbers?

Hero

Best ResponseYou've already chosen the best response.1Add that to your set builder notation.
