PLZ HELP-WILL FAN AND MEDAL x + y = 5 y = one halfx + 2 If the two equations are graphed, at what point do the lines representing the two equations intersect? (2, 5) (5, 2) (2, 3) (3, 2)

Do you have any thoughts on how to start?

Easy math.
JoannaBlackwelder
  • JoannaBlackwelder
Maybe it is for you, @JacobRobloxian but I'm sure you didn't know how to do a problem like this at some point.
anonymous
  • anonymous
Im trying to solve it hold on.
JoannaBlackwelder
  • JoannaBlackwelder
:-)
anonymous
  • anonymous
I would say either c or d but
JoannaBlackwelder
  • JoannaBlackwelder
Give steps if you want to help, not letter answers, @JacobRobloxian

Well first solve for x, then plug it in either of the equations to get a corresponding y, it doesn't matter which one you pick.
JoannaBlackwelder
  • JoannaBlackwelder
|dw:1439928926327:dw| I would substitute what y equals in for the other equation.
anonymous
  • anonymous
When you get the (x,y) that will be the point where the lines intersect.
JoannaBlackwelder
  • JoannaBlackwelder
|dw:1439928993220:dw| See how I subbed that in?
anonymous
  • anonymous
yes i do
JoannaBlackwelder
  • JoannaBlackwelder
Sweet :-) Can you solve for x?
anonymous
  • anonymous
yes, give me one sec to work it out :)
JoannaBlackwelder
  • JoannaBlackwelder
Sure thing :-)
anonymous
  • anonymous
I'm having a hard time solving it :0

Try and plug in one of your choices for the x and y values. He gave you the right equations to help you input those values from your choices.
JoannaBlackwelder
  • JoannaBlackwelder
|dw:1439929323531:dw| First combine like terms.
anonymous
  • anonymous
ok i see now
JoannaBlackwelder
  • JoannaBlackwelder
|dw:1439929409830:dw| :-) One more step of combining like terms

@JoannaBlackwelder Great work, thank you for completely running through it with this poster! (:
JoannaBlackwelder
  • JoannaBlackwelder
Thanks :-) and you're welcome
JoannaBlackwelder
  • JoannaBlackwelder
Any ideas for the next step?
anonymous
  • anonymous
is that 2 slashed out or no?
JoannaBlackwelder
  • JoannaBlackwelder
I'm not sure what you mean. I subtracted 2 on both sides. How do you think that would simplify?
anonymous
  • anonymous
divide on each side??
JoannaBlackwelder
  • JoannaBlackwelder
Yep, good. What does that give?
anonymous
  • anonymous
im not sure what to divide on each side though
JoannaBlackwelder
  • JoannaBlackwelder
|dw:1439929759309:dw| 3/2 is multiplied by x, so we need to divide by 3/2 to get x by itself.
JoannaBlackwelder
  • JoannaBlackwelder
|dw:1439929805492:dw| Can you simplify that fraction?
anonymous
  • anonymous
right, ok ok i get it now, but no i can't do that
anonymous
  • anonymous
Your x/y value which was not used. 3/2x = 3 3/2x into 3. Consider, 3/2 x 2 = 6/2 6 divided by 2 is 3. Which would give you your answer. 2/1 = 2 3/2 * 2/1 6/2 x = 2
JoannaBlackwelder
  • JoannaBlackwelder
Yep, that is one method :-)
anonymous
  • anonymous
ohhh i see u turn the 2 into a fraction thanks @Mikeyy1992 and @JoannaBlackwelder
anonymous
  • anonymous
but i still don't get the graphing points
anonymous
  • anonymous
Of course, we're here to help, there are many methods to solve a puzzle, ever need help tag us. You're welcome! (: What do you not get?
JoannaBlackwelder
  • JoannaBlackwelder
The graphs intersect at the solution.
JoannaBlackwelder
  • JoannaBlackwelder
We found the x coordinate to be 2 so far.
anonymous
  • anonymous
ok i see
JoannaBlackwelder
  • JoannaBlackwelder
So now we need to find the corresponding y value.
JoannaBlackwelder
  • JoannaBlackwelder
:-)
anonymous
  • anonymous
got it
anonymous
  • anonymous
:)
JoannaBlackwelder
  • JoannaBlackwelder
Great!
anonymous
  • anonymous
oh no i mean like yes we have to get the y value sorry :)
JoannaBlackwelder
  • JoannaBlackwelder
It's good. We can plug that x value into either equation and solve for y.
anonymous
  • anonymous
ok
anonymous
  • anonymous
so what is y
anonymous
  • anonymous
@Mikeyy1992
anonymous
  • anonymous
All you have to do is plug in x into the equation you have already. (:
