anyone please be nice enough to help me
ok so do you know what the question is asking?
I dentify which of the given points are solution to the following linear equations
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
Does 6 + 8 = 12 ?
Correct, so cross off option A as not being an answer.
for b is no
3x + 2y = 12 Substitute 3 for x and 2 for y and see if a true statement results.
Post what you get, okay?
Its c and d
I also did number 2 but im struggling with number 3.
I agree with those answers for #1.
For number 2 its a and c
im struggling with number 3
x + y = 6 and (2,?) means that you are to substitute 2 for x and then crank out the value of y.
2 + y = 6 y = ?
is that right ?
so would it be A.(2,4) and B(0,6) and c (6,0)
Yes, (2,4). Sorry that I was late in responding.
Hold on a sec while I check B and C
That is what I got. >>> and B(0,6) and c (6,0)
for number 5. i dont get c
Look at the top of the thead and meet my friend, Wolf 1728. He is an excellent helper!
can you help me with number 5 with letter c please
Okay if I can find it.
its on page 9
Did you find it ?
page 9 question 3?
no question 5
okay question 5
i dont get letter c
for a i got (2,-2) b (0,-8) c ( , 0) i dont know whats for c ?
yes for 5
Since y=0 then you could write the equation as 3x = 8 then x=8/3
so i would have to multiply 3 times 8/3 ?
it actually equals 8
8 divided by 3
why does it equal 8?
8 divided by 3 = 2.66666...
multiply 3 times 3/8
3x = 8 right?
check in your caculator 3x8/3-0=
3x -y = 8 y = 0 So 3x = 8
therefore x = 8/3
so i got (8/3,0)
its right ?
now i need to do graphing ughh
i did number 6 already
could u be nice enough to help me still ?
i hope i dont bother u
yes for question 6.
i mean question 7.
I got a phone call - might be done in about 10 minutes
its page 9 question 7
Did you find it?
You have to make a graph of x<7 ?
|dw:1444271553126:dw| i only ploted 7 because i dont know what to do next
I'll make the graph
wouldnt there be coordnates
Yes, the red line is the graoh
All you need to do is graph the x values. Since NO y values are mentioned, there are NO y values to plot.
okay so it would just be the line right the red one straight
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.
