A. True; the expressionas are the same for all values of variables B. False; the expressions are never the same ******
C. Open; there is a varible
(12)Which equation is an Identity
A. 7 - (9x + 3) = -9x - 4
B. 6m - 5 = 7m +5 - m
C.10p + 6 - p = 12p - 3 (p - 2) *****
D. 3y + 2 = 3y - 2
(13)Which equation has no solution?
A. 5w + 4 - w = 9w -2 (w - 2)
B. 3x - 5 = 3x + 8 - x
C. 7z + 6 = -7z - 5
D. 4y + 5 = 4y - 6 *****

A. 4
B. -4
C. infinitely many solutions
D. no solution *****
Answer is *****, if it is wrong can you tell me how to solve it, Thankyou
@mixikamo is wrong i got a 3/19! Please do not use their answers.
1) C
Other answers are correct.
Is this for the unit 3 lesson 9 test
- 4 y + 8 = 4 ( 2 y - 2 ) - 2 ( - 16 + 8 y )
- 4 y + 8 = 4 ∙ 2 y + 4 ∙ ( - 2 ) - 2 ∙ ( - 16 ) - 2 ∙ 8 y
- 4 y + 8 = 8 y - 8 + 32 - 16 y
- 4 y + 8 = 8 y - 16 y - 8 + 32
- 4 y + 8 = - 8 y + 24
Add 8y to both sides
- 4 y + 8 y + 8 = - 8 y + 8 y + 24
4 y + 8 = 24
Subtract 8 to both sides
4 y + 8 - 8 = 24 - 8
4 y = 16
y = 16 / 4 = 4
Thankyou, and can you explain to me how it is c
And i have one more question that i need help on
Solve the following equation.
-4y + 8 = 4 (2y - 2) -2 (-16 + 8y)
A. y= -4
B. y= 4
C. y= -2
D. y= -6
bruuh I'll post the answers when I finish the test lmao
help I just got a 9/19😭
Mathematical statements with one or more VARIABLES
are called open sentences.
In statement:
4y + 8 = 6y + 3
variable is y
I CANT FIND THE ANSWERS... these answers are apparently not for connexus because my quick check/test only has five questions.
What are the correct answers???
your all to stupid to read what it says after you get the questions wrong just read what it says and type that.
is this true??????????????????????
i need help i suck at math -_-
Help plsssssss
lmao they change up the answers so students cant fill in the answer sheet we provide ourselves. IT WAS, IS, AND ALWAYS WILL BE MIXED UP AND DIFFERENT FOR EVERY CONNEXUS USER
if you are taking the connexus, i just took it. they redo the questions everytime you retake the test/quiz. here are the correct answers:
c
