@TheSmartOne @immanuelv

Answer 1

there are two answers?

Answer 2

Distribute

Answer 3

yup only 2 answers

Answer 4

okay, so ya know how i gave you wrong answers before...well that's cause i misread the problem...now i understand it, so yea, i can help you better...lol

Answer 5

i seee :D

Answer 6

But first, do what @TheSmartOne said...

Answer 7

24x-18-10x=??

Answer 8

^^^

Answer 9

*hint* the solutions with same slope wont be the answer :D

Answer 10

^ that's a good hint

Answer 11

but not always necessarily true

Answer 12

YOU GUYS ARE KILLING ME ITS HALLOWEEN IM DOING HW BE MY CANDY AND ANSWER THIS PLEASE

Answer 13

or is it...hold on

Answer 14

unless they have the same y intercept.. but not here xD

Answer 15

im below the food chain @Bossimbacon i cant disobey Mathletes xD

Answer 16

no...actually for this one, the slopes can be the same...you are finding ones that will produce no solutions, not infinte

Answer 17

lol @immanuelv

Answer 18

examples:
4x + 1 = 4x +2
No solution

Answer 19

4x +1 = 4x +1
inifnite solutions

Answer 20

haha well its the ones with same slope.b for the answer :d

Answer 21

i have put the answers in my answer as a treat for ya :D

Answer 22

THANKK YOU SO MUCH @immanuelv so b and d'

Answer 23

A is one of the answers becaue
\[14x - 18 \neq 14x - 15\]

Answer 24

b is the other answer

Answer 25

b is one of them... not d i messed up the :D sorry :(

Answer 26

so a ahhhh

Answer 27

tyyy guys

Answer 28

^_^ now im gonna be in trouble

Answer 29

because....
2(7x - 10)
14x - 20

Answer 30

and
\[14x - 18 \neq 14x - 20\]

Answer 31

6(4x – 3) – 10x =
24x-18-10x=
14x-18
now we can try the choices to knew which are true
A. 14x – 15
14x-18=14x-15
14x-14x=-15+18
which gives that 0=3 which is impossible so we have no solution
so A is one of the answers

B. 2(7x – 10)
14x-18=14x-20
14x-14x=-20+18
which gives that 0=-2 which is impossible so we have no solution
so B is the second answers
so the answers are A and B

to make sure that the answers are A and B let us try to see C and D
C. 15x – 14
14x-18=15x-14
-18+14=15x-14x
-4 =x so we have exactly one solution so C is not one of the answers

D. 2(7x – 9 )
14x-18=14x-18
14x-14x=-18+18
0=0 so we have infinitly many solutions so D is not one of the answers
so we are sure that the answers are A and B

Answer 32

6(4x – 3) – 10x =
24x-18-10x=
14x-18
now we can try the choices to knew which are true
A. 14x – 15
14x-18=14x-15
14x-14x=-15+18
which gives that 0=3 which is impossible so we have no solution
so A is one of the answers

B. 2(7x – 10)
14x-18=14x-20
14x-14x=-20+18
which gives that 0=-2 which is impossible so we have no solution
so B is the second answers
so the answers are A and B

to make sure that the answers are A and B let us try to see C and D
C. 15x – 14
14x-18=15x-14
-18+14=15x-14x
-4 =x so we have exactly one solution so C is not one of the answers

D. 2(7x – 9 )
14x-18=14x-18
14x-14x=-18+18
0=0 so we have infinitly many solutions so D is not one of the answers
so we are sure that the answers are A and B
