Does anyone have the answers to the Rational Expressions and Functions Unit Test? I can't focus at all right now
Y’all are so brave taking one for the team like this😭
I used everybody's answers and got an A. LMFAO
6.8.1 Test: Rational Express &Func PI
1. D -4x^2+2x+2
2. D x^2+2x2
3. A 150/x
4. B 1/4+x where -4,0
5. A 5/7+x where 0,-7
6. A 1/x-3 where 3,-7
7. B x-6 where -3
8. C 4/3a^2 where a not 0
9. C (x-5)(3x+2)
10. D x+2/x-8
11. A (x+3)(x-1)/x-3
12. D 4m^4-5m^2
13. A 5d^6-3d+2d^2
14. A -5x-7/x+3
15. A-2x+9/(x-3)(x-2)
16. B 14x+31/(x-1)(x+4)
17.A x=2
18. B x=9/2
19.C x= -3/4 or 2/
20 C 4.44 hrs
21. D 8.47 he
22. C direct var
23. C x-16
looks like the questions might be randomized... just our luck
lmao got 8/23 using love cats here are the real answers
1. -4x^2 + 2x+ 1
2. x^2 + 2x+2
3. 270/x
4. 1/ 4+x; where x ≠ -4,0
5. -12/ 1+8x; where x ≠ - 1/8, 0
6.1/ x+1; where x ≠ -1, -5
7. x-1; where x ≠ -4
8. 3/ 5a^3; where a ≠ 0
9. (x-5) (3x+2)
10. x-4/x-1
11. (x+3)(x-1)/(x-3)
12. 4m^4 - 5m^2
13. -w^5+ 2w^3+ w
14. -5x - 7/ x+3
15. 3x-33/ (x+7) (x-2)
16. 10x +26/ (x-3) (x+5)
17. x=-3
18. x= - 23/6
19. x= -3/4 or x= 2/3
20. 6.15 hours
21. about 8.47 hours
22. direct variation; y =5x
23. x=12
HOPE THIS HELPS THESE ARE ALL CORRECT!!!!
I got a 65.2% with love cats answers.
It wasn't the 100% I was looking for but it's better then what I would have scored guessing.
