campbell_st · Answer

you may want to retype the question, as there doesn't appear to be a fraction

anonymous · Answer

Answer choices for #1: 2y/2y+3 or y/(2)(y+3)
#2: -3 or 3

anonymous · Answer

Is that better? @campbell_st

campbell_st · Answer

takes a fraction... so looking at the 2 terms in the denominator... do 2y and 3 have a common factor...?

anonymous · Answer

No

campbell_st · Answer

can I check is the fraction 

1. $$\frac{4y}{8y + 24} -1 $$

anonymous · Answer

What?

campbell_st · Answer

well the original fraction you posted has -1 at the end...

anonymous · Answer

No, that's an exponent.

campbell_st · Answer

ok... so its 

$$4y (8y + 24)^{-1}$$

campbell_st · Answer

which can be written as 

$$\frac{4y}{8y + 24}$$

4 is a common factor... so divide every term by 4

what do you get...?

anonymous · Answer

y/2y+6

campbell_st · Answer

great.... and is ther a common factor in the denominator..?

anonymous · Answer

2?

campbell_st · Answer

great so then the factored form is a little weird but its the 2nd of your choices... 

so looking at 

y + 3

what value of y makes the expression zero..?

anonymous · Answer

Dude I have no idea.

campbell_st · Answer

well solve this Dudette

y + 3 = 0

campbell_st · Answer

the answer you get will be the restriction for the denominator

anonymous · Answer

-3

anonymous · Answer

@campbell_st

campbell_st · Answer

correct... so now you have the solution.... 

restrictions in fractions are the value(s) that make the denominator zero.... 

so looking at the original question you needed to solve

8y + 24 = 0

its the same answer as the simplified version.

anonymous · Answer

That doesn't make sense

campbell_st · Answer

ok.... tell be what happens when you enter this into a calculator 

$$2 \div 0 =$$

anonymous · Answer

campbell_st · Answer

no actually pick up a calculator and do it

anonymous · Answer

Lol no. I don't have time for this. You're making me do extra work that is totally unnecessary.

campbell_st · Answer

you answer is to the problem 

$$0 \div 2 = 0$$

campbell_st · Answer

well it is necessary as its fundamental to the questions you are asking.

anonymous · Answer

Not really. I'm not gonna do extra work when I have enough as it is.

campbell_st · Answer

is a simple task... use a calculator http://web2.0calc.com/ here is an online on... tell me what happens with the calculation $$2 \div 0 =$$

anonymous · Answer

Nah

ribhu · Answer

y not equal to -3

anonymous · Answer

@ribhu English, please.

ribhu · Answer

y would not be equal to -3

anonymous · Answer

Soooo what's that mean?

campbell_st · Answer

that's a solution you found a lot earlier..

ribhu · Answer

what do u want exactly?

anonymous · Answer

Okay, what about the other one then? @ribhu obviously I want the answer.

campbell_st · Answer

you have found both answers... you just need to go back and read thinks...
