sometimes

anonymous · Answer

Here is another question I don't get. It's an essay question! :(
Part 1:
Solve each of the quadratic equations below and describe what the solution(s) represent to the graph of each. Show your work to receive full credit.

y = x2 + 3x + 2 
y = x2 + 2x + 1
Part 2:
Using complete sentences, answer the following questions about the two quadratic equations above.
Do the two quadratic equations have anything in common? If so, what? 
What makes y = x2 + 3x + 2 different from y = x2 + 2x + 1?

Help me!!! Someone who has taken Algenra before, please? :)

precal · Answer

sometimes is your answer for the first one

precal · Answer

the number of solutions depends on how many times the equations cross each other

precal · Answer

|dw:1350850353630:dw|one solution because they cross once

anonymous · Answer

So it's sometimes?

precal · Answer

|dw:1350850370841:dw|parallel lines never cross so it is no solution
yes sometimes, I am explaining why

precal · Answer

|dw:1350850411715:dw|pretend I drew 2 straight lines that overlap each other, they have infinitely many solutions because they cross is so many places

Oh, I get it now! :) Did you take Algebra before?

precal · Answer

yes

anonymous · Answer

I think it's really hard! :(

precal · Answer

gets easier, just do your homework and listen to the lectures

anonymous · Answer

Oh..lol! I'm taking it online though! (

Do you understand essay questions?

precal · Answer

yes why don't u graph it and see if they cross

anonymous · Answer

Okay. :) Is there an easier way t do it?

precal · Answer

yes by graphing it

anonymous · Answer

Okay, I will do that! :) 
There are some more I'm confused on, multiple choice questions, though.

precal · Answer

they cross in one place.  You could use the quadratic formula to solve them both

precal · Answer

good luck :)  close this problem and post a new one
