Question

Part 1:
For the following system of equations, write your own real world scenario that describes what is happening. Use complete sentences and correct grammar in your scenario.

Part 2:
Solve the system and explain what the results mean according to your scenario.

2x + y = 11
3x + 4y = 24

Answer 1

do you have florida virtual school?

Answer 2

yes

Answer 3

ohh that sucks but so do i, thats how i recognized it because im taking algebra too.

Answer 4

oh cool

Answer 5

do u know what 2 do ?

Answer 6

yea what module is this? soo maybe i can go to it and show you my answer....but if i do please do write exactly what i did..

Answer 7

ok it's module 6, 6.10

Answer 8

2x + y = 11
3x + 4y = 24
take equation 1 and substitute into 2:
y = 9 - 2x
3x + 4(9 - 2x) = 26
3x + 36 - 8x = 26
-5x = -10
x = 2
y = 9 - 4
y = 5

(2,5)

*i did part 1 not 2 on the test Sorry!, but you can just write whatever

Answer 9

*i mean i did part 2 not part 1..

Answer 10

ok

Answer 11

yea your welcome and if you need any help jusst tag me like this @Snapbacklive
because i go on here everyday , because i also need help on flvs,im on module 8(:

Answer 12

what time do you come on here

Answer 13

i come like at 11am, and i usually stay till late but idk about tomorrow because i might go out with friends soo yea... but ill try! because i start high school next week and i want to get this over with soo that's why im always on haha(:

Answer 14

but if you want start on the module 7 pre test now so when you get to 7.01 you can ask me w.e you need help on because im going to stay up late today

Answer 15

well i have one more question

Answer 16

sure what is it?

Answer 17

You graph a system of equations and the two lines intersect one another. Explain what this tells you about the:

solution to the system
the two equations
the result if the system was solved algebraically

Answer 18

from what module or test is this?

Answer 19

same one

Answer 20

ok so if the lines are on top of each each other how many solutions is it?

Answer 21

There is an error in your solution @Rkb<3NH

Answer 22

how?

Answer 23

which one

Answer 24

When he isolated y in the first equation he typoed and used 9 instead of 11

Answer 25

what do you mean?

Answer 26

2x + y = 11
y= 11 - 2x Not y = 9 - 2x

Answer 27

ohh!! okay im sorry..wait il fix it noww

Answer 28

The step by step was a good think as it makes it easy to see an error.

Answer 29

2x + y = 11
3x + 4y = 24
take equation 1 and substitute into 2:
y = 9 - 11x
3x + 4(9 - 11x) = 26
3x + 36 - 44x = 26
-41x = -10

@radar can you help me i got stuck(:

Answer 30

2x+y=11 then y = 11 - 2x substituting in the second equation you get
3x + 4(11-2x)=24
3x + 44 -8x = 24
-5x=-20
x=4

did you follow?

Answer 31

ohh haha yea wow how easy is it too make a simple mistake but thank you(:

Answer 32

No problem, it is obvious you know what you're doing, but a typo can really mess u up. Good luck with these.

Answer 33

Thanks for helping out(:

Answer 34

how about my question

Answer 35

That was part 2 of your question....I think.

Answer 36

You graph a system of equations and ***the two lines intersect one another.*** Explain what this tells you about the:
1.solution to the system
2.the two equations
3.the result if the system was solved algebraically

* for #1:
the system will have infinite solutions because the one solution because the lines are perpendicular so they only intersect once.

Answer 37

You substitute the value of x (which is 4) into the 2x + y =11
getting 8 + y =11
y=11-8=3
x=4, y=3

Answer 38

If the lines do intersect there is one solution for the system. If the lines do not intersect (meaning they are parallel) there is no single solution for that system.

Answer 39

for #2:
the equation could be
2y = 2x + 8
2x + 2y = 4

Answer 40

for # 3:
If the system was solved algebraically, you'll probably end up with, such as 0 = 0.

Answer 41

thank you

Answer 42

your welcome(: anymore help?

Answer 43

no i will have more questions tomorrow, thanks for ur help

Answer 44

okay (:
