Best ResponseYou've already chosen the best response.0So is it: a)the first one b)the second one c)or both

Best ResponseYou've already chosen the best response.0but most likely the first one

Best ResponseYou've already chosen the best response.0any equation in the form of y=mx+b is linear

anonymous

Best ResponseYou've already chosen the best response.0i thought it was supposed to be ax+by=c

Best ResponseYou've already chosen the best response.2Try re writing both in linear form.

anonymous

Best ResponseYou've already chosen the best response.0For the first one, I think it is 3x4y=12, but I'm still not that sure how I got 12.

Hero

Best ResponseYou've already chosen the best response.2.Please show the work you did to get that.

anonymous

Best ResponseYou've already chosen the best response.0I crossmultiplied: 3(x) and 4(y), which gave me 3x4y. And then I guess I multiplied the 3 and 4 and got 12. So 3x4y=12

Best ResponseYou've already chosen the best response.0Is there a way you can post the questions and options in one post?

anonymous

Best ResponseYou've already chosen the best response.0I do not know. Do you want the options?

Best ResponseYou've already chosen the best response.2The approach you took is not "algebraic" and would be considered an incorrect approach.

anonymous

Best ResponseYou've already chosen the best response.0Oh sorry could you please help me to do it the correct way?

Hero

Best ResponseYou've already chosen the best response.2You don't cross multiply The difference of two fractions.

Hero

Best ResponseYou've already chosen the best response.2Multiply both sides of the equation by the LCD

anonymous

Best ResponseYou've already chosen the best response.0You mean the Least Common Denominator?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Ok let me try. Don't leave, please.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0But there are 2 fractions on one side of the equation, so how will I find the LCD?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0I'm sorry for being so dumb.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Are you there @Hero ?

Hero
 one year ago
Best ResponseYou've already chosen the best response.2I'M here. The LCD is twelve. you should watch a tutorial on how to find the LCD of two fractions going forward though

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Your talking about the first equation, right?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Ok so I should multiply 12 with both the fractions and 1, right?

Hero
 one year ago
Best ResponseYou've already chosen the best response.2Don't forget to cross cancel where possible.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0So: 12x/4  12y/3 = 12 3x  4y = 12

Hero
 one year ago
Best ResponseYou've already chosen the best response.2So you know the first equation is linear since it has the general linear form.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0OK NOW I GET IT! Isn't 3x  4y = 12 a linear equation in standard form, which is ax  by = c

Hero
 one year ago
Best ResponseYou've already chosen the best response.2Now try writing the second equation In the same form.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Ok just wait. Please don't leave.

anonymous

Best ResponseYou've already chosen the best response.0So 10 is the LCD for the second equation, right?

Hero
 one year ago
Best ResponseYou've already chosen the best response.2Tell me what is in the denominators of the fractions of the Second equation?

Hero
 one year ago
Best ResponseYou've already chosen the best response.2Explain how 10 Can be the LCD of x and y.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0OH WAIT SO YOU CANNOT FIND THE LCD FOR THE SECOND EQUATION BECAUSE THEY'RE VARIABLES. So that means it is NOT A LINEAR EQUATION, right?

Hero
 one year ago
Best ResponseYou've already chosen the best response.2Actually, there IS an LCD for denominators x and y.

Hero
 one year ago
Best ResponseYou've already chosen the best response.2You find it the same way you found the LCD of 3 and 4

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yay! But the second equation isn't a linear equation, right?

Hero
 one year ago
Best ResponseYou've already chosen the best response.2You have to SHOW that it isn't

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0I don't actually know how to do that.

Hero
 one year ago
Best ResponseYou've already chosen the best response.2Try to write it in linear form. You already found the LCD. Remember what to do afterwards?

anonymous

Best ResponseYou've already chosen the best response.0OH YEAH! Just give a minute. I'll solve it out. Just stay there.

anonymous

Best ResponseYou've already chosen the best response.0So: 5xy/1x  3xy/1y = 7xy

Best ResponseYou've already chosen the best response.2Factors of one that allow you to Simplify expressions.

Hero
 one year ago
Best ResponseYou've already chosen the best response.2You have good intention but that is not the correct Simplification.

Hero

Best ResponseYou've already chosen the best response.2What does x/x =1 mean to you?

Hero
 one year ago
Best ResponseYou've already chosen the best response.2Well that would imply that x=1 but x is a variable

Hero

Best ResponseYou've already chosen the best response.2Basically for any fraction, if you have a factor in the numerator and the same factor in the denominator of a fraction, then the factors cancel to just 1

Hero
 one year ago
Best ResponseYou've already chosen the best response.2The factors together Cancel to get 1 but a factor by itself does not equal one.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Oh ok but I don't know where this going.

Hero
 one year ago
Best ResponseYou've already chosen the best response.2For example, 7/7 =1 but 7 ≠1

Hero
 one year ago
Best ResponseYou've already chosen the best response.2The way it's going is I can cancel any factor that occurs in both the numerator and denominator Without changing the value of the fraction.

Hero

Best ResponseYou've already chosen the best response.2So you should have ended up With:

Best ResponseYou've already chosen the best response.0Thank u very much @Hero ur the best.

Hero

Best ResponseYou've already chosen the best response.2Which can also be written as 3x + 5y = 7xy

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so it is not a linear equation

Hero
 one year ago
Best ResponseYou've already chosen the best response.2But it is NOT Linear because 7xy is clearly not a constant,

Hero
 one year ago
Best ResponseYou've already chosen the best response.2So, yes, correct, not linear.
