Which graph represents the solution to the given system?
y=-x+5
y=1/4x+10
Im rlly behind and need some help on the test .-.
@bruh bold of you to assume We are having kids
@bruh has now lost the ability to have children. Have a good day students! :)
can y'all just type the question out and then put the answer so there's no debating on who's right and who's wrong😭

good luck, guys! <3
its 2021 now and nobody knows if the answers are correct :/
In Eq2, replace Y with -x + 5:
-x + 5 = x/4 + 10.
Multiply both sides by 4:
-4x + 20 = x + 40,
X = -4.
In Eq1, replace X with -4 and solve for Y:
Y = -(-4) + 5 = 9.
Solution:(-4, 9).

couldve really use the answers right about now :(
im so confused right now
The test is different for everybody but Bobby flay got me a 73%
Henery2 do you know the other answers the the test?
It would help if you put the questions with the answers that way we know which test you are talking about, I'm about to submit my answers and see what I get then I'll come back and put the questions and answers for ya'll. (I am using :3 answers and hopefully they are right)
bobby flay is wrong i got a 65%
I swear people need to not just put the lettersssss. It might take me all morning but I will get the answers for u guys.
In the mean time, study for ur finals, there no way to check answers for that.
peace helper’s answers are completely wrong and i got 14/23 (60.9%)
I know the answers but i closed the answers out so open a browser with the same lesson on it and get them wrong and you can look at your answers you missed then reuse the answers thankmelatermates :D
@ shakes its better than a zero that's for shore!!!
I'm pretty sure the test differs in each state, the test isn't changing, its the location of the students that makes it different.
Leoヾ(◍°∇°◍)ﾉﾞ i used your answers and got a 47.8% i think there is a different test every person
BoBBY Flay got me 15/23
i got a 19/23 or an (82.6)

I have 25 questions.😑
I used the answers by k and got 52 percent, I just don't recomend trying to find answers on this quiz they are all different.
thx is wrong i got 30.47%
aaaaaaaaaaaaaaa i just want answers
what r the answers in california
After the pain of trying to find the answers, I have finished the test with an 85%. To help the rest of you, here are the answers to the 20 question test, Midwest.

18) Mary is selling her crafts to earn money. 6x+10y<120
Answer: B: The graph should almost be completely shaded, with a small white space in the bottom left corner.
19) Which graph represents this system of inequalities? y<x+4 2x+y<-4
Answer: A: Most of the bottom left side should be shaded, with only two little corners remaining white.
20) Which graph represents this system of inequalities? y<-2x-3 y>3x+2
Answer: D: Most of the left side should be shaded, the areas closest to the right side should still be white.
Good luck, again, these are the answers to the Systems of Equations and Inequalities Unit Test, Unit 3 lesson 9. This is the 20 question test for the Midwest region.
brylen is wrong i got a 14/23
@Anonymous how old are you, 25?!?!?!?
put the answers and i mean the words, not just a b c or d. also test changed
Thank you @ Bobby Flay
Can some just please give me the answers
that's true @unknown who's got the answers for the central coast
wowww i got 47.8 on it thanks to @leo
Hey I got the answers let me just finish the test to make sure they are right @CAY
i have 37 questions man.
I have 37 questions on my test too
2023 unit 8 Semester B Exam and Review
LESSON 2
Semester B Exam
there is no test for unit 7 anymore cause it got fused with the unit 8 exam
it would be conveinent if you could give the answers now
klPillow got me a 82.6 w fr
for me the corrections are 2. (a) 2 lines passing through 4 and 7 and ending at -2 and -4
7. (c) on the very right side shaded 4 and 5
16. (b) 750 t shirts
23. (b) y<or equal to x - 5 and 7 > or queal to 3x - 2
The questions shuffle so they're never in the same order. None of these test answers help anyone. I don't think I wanna get math help from the idiots who didn't even catch this...
is @thx right?
