I dentify which of the given points are solution to the following linear equations
Directrix
  • Directrix
Is this the question?
wintersuntime
  • wintersuntime
yes
Directrix
  • Directrix
To help you get started, take the given equation and fill in 2 for x and 4 for y and see if you get a true result. 3x + 2y = 12 3*2 + 2*4 = 12 ? yes or no @wintersuntime
Directrix
  • Directrix
Does 6 + 8 = 12 ?
wintersuntime
  • wintersuntime
no
Directrix
  • Directrix
Correct, so cross off option A as not being an answer.
wintersuntime
  • wintersuntime
for b is no
Directrix
  • Directrix
3x + 2y = 12 Substitute 3 for x and 2 for y and see if a true statement results.
Directrix
  • Directrix
Post what you get, okay?
wintersuntime
  • wintersuntime
Its c and d

@Directrix
wintersuntime

I also did number 2 but im struggling with number 3.
Directrix
  • Directrix
I agree with those answers for #1.
wintersuntime
  • wintersuntime
For number 2 its a and c
wintersuntime
  • wintersuntime
im struggling with number 3
Directrix
  • Directrix
x + y = 6 and (2,?) means that you are to substitute 2 for x and then crank out the value of y.
Directrix
  • Directrix
2 + y = 6 y = ?
wintersuntime
  • wintersuntime
4?
wintersuntime
  • wintersuntime
is that right ?
wintersuntime
  • wintersuntime
so would it be A.(2,4) and B(0,6) and c (6,0)
wintersuntime
  • wintersuntime
@Directrix
wintersuntime
  • wintersuntime
hello?
wintersuntime
  • wintersuntime
@Directrix
Directrix
  • Directrix
Yes, (2,4). Sorry that I was late in responding.
Directrix
  • Directrix
Hold on a sec while I check B and C
Directrix
  • Directrix
That is what I got. >>> and B(0,6) and c (6,0)
wintersuntime
  • wintersuntime
okay
wintersuntime
  • wintersuntime
its okay
wintersuntime
  • wintersuntime
for number 5. i dont get c

wintersuntime
  • wintersuntime
no question 5
wolf1728
  • wolf1728

wintersuntime
  • wintersuntime
yes for 5
wintersuntime
  • wintersuntime
letter c

Since y=0 then you could write the equation as 3x = 8 then x=8/3
wintersuntime
  • wintersuntime
so i would have to multiply 3 times 8/3 ?
wolf1728
  • wolf1728
x=2.666666...
wintersuntime
  • wintersuntime
it actually equals 8
wintersuntime
  • wintersuntime
8 divided by 3
wolf1728
  • wolf1728
why does it equal 8?
wintersuntime
  • wintersuntime
because 3x8/3-0=8
wolf1728
  • wolf1728
8 divided by 3 = 2.66666...
wintersuntime
  • wintersuntime
multiply 3 times 3/8
wolf1728
  • wolf1728
3x = 8 right?
wintersuntime
  • wintersuntime
no 8/3
wintersuntime
  • wintersuntime
check in your caculator 3x8/3-0=
wolf1728
  • wolf1728
3x -y = 8 y = 0 So 3x = 8
wintersuntime
  • wintersuntime
yes
wolf1728
  • wolf1728
therefore x = 8/3
wintersuntime
  • wintersuntime
yes
wintersuntime
  • wintersuntime
so i got (8/3,0)
wintersuntime
  • wintersuntime
its right ?
wolf1728
  • wolf1728
yes :-)
wintersuntime
  • wintersuntime
yay
wintersuntime
  • wintersuntime
now i need to do graphing ughh
wintersuntime
  • wintersuntime
i did number 6 already
wintersuntime
  • wintersuntime
could u be nice enough to help me still ?
wolf1728
  • wolf1728
graphing?
wintersuntime
  • wintersuntime
i hope i dont bother u
wintersuntime
  • wintersuntime
yes for question 6.
wintersuntime
  • wintersuntime
i mean question 7.
wolf1728
  • wolf1728
I got a phone call - might be done in about 10 minutes
wintersuntime
  • wintersuntime
okay
wintersuntime
  • wintersuntime
https://www.mathematicsvisionproject.org/uploads/1/1/6/3/11636986/sec1_mod2_systems_se_71713.pdf
wintersuntime
  • wintersuntime
its page 9 question 7
wintersuntime
  • wintersuntime
Did you find it?
wolf1728
  • wolf1728
You have to make a graph of x<7 ?
wintersuntime
  • wintersuntime
|dw:1444271553126:dw| i only ploted 7 because i dont know what to do next
wolf1728
  • wolf1728
I'll make the graph
wolf1728
  • wolf1728
Here it is:
wintersuntime
  • wintersuntime
wouldnt there be coordnates
wolf1728
  • wolf1728
Yes, the red line is the graoh
wolf1728
  • wolf1728
All you need to do is graph the x values. Since NO y values are mentioned, there are NO y values to plot.
wintersuntime
  • wintersuntime
okay so it would just be the line right the red one straight
wolf1728
  • wolf1728
Don't forget to include the circle at x=7. Why do you need the circle there instead of just continuing the line to 7? The equation says x is less than 7 so x can never equal seven.
wintersuntime
  • wintersuntime
okay thanks
wolf1728
  • wolf1728
Okay then
