Just letting y'all Connexus people know, this semester some of the teachers have been scrambling the problem sets to keep people from just punching in letters off of here. These people's answers were probably right for their problem set, but not for yours. I'd advise just opening Symbolab and Desmos and letting them do the work.
all correct. I hope you know why on each.
Everyone has different test jus gotta find which on they have
answers, they are, scrambled? i think? anyways, when u a start a test, the answers get scrambled and there are a few of questions that u dont see in there bc they are hidden for others
1. (-3, 7)
2. (-2, -9.5)
3. Infinitely many
4. None
5. Infinitely many
6. None
7. Vertical Line on (3, 0)
8. Horizontal Line on (0, -2)
9. y => 20
2x + 2y =< 100
10. 3 Hours
11. $1.25 Hot dog ; $0.75 Soda
12. No Solution
13. Infinitely Many Solutions
14. (1.5, 10)
15. (28, -20)
16. 100 Lawns
17. 70 mL to 35 mL
18. (1, 2) (0, -2)
19. (-10, 0) (10, 8) Shaded Above
20. 5x + 7y => 140
21. Middle bottom shaded
22. Left side shaded
23. y =< x - 5 and y => -3x - 2
just letting everyone know you can use Desmos for the graph stuff it doesn't count as cheating and it's easy it gives you correct answers but Sniper is right i think for 1-9 that's all i had from their questions
