Question

Which of the following points are solutions to the system of inequalities shown below?

y>6x+7
y<6x+9

Answer 1

A. (-4, 32)
B. (3, 26)
C. (3, 25)
D. (4, 33)

Answer 2

C

Answer 3

theres more than 1 answers

Answer 4

it's not C as that would make 25>25 and that's false.

Answer 5

Its B

Answer 6

I don't understand this at all

Answer 7

plug them in X and Y

Answer 8

Can you please explain this?

Answer 9

put the values you have supplied into the each eqn i.e. for the first one
y>6x+7

32 > 6(-4)+7
32 > -24 + 7
32 > -17

Thats true now do the same thing for the other eqn and if they are both true thats an answer :D

Answer 10

the values are in the format (x,y) so substitute (-4,32) x=-4 y=32

do you see

Answer 11

Kind of

Answer 12

The answers are B and D
26>6(3)+7 TRUE
26 < 6(3) + 9 TRUE

also

33 > 6(4)+7 TRUE
33 < 6(4) +9 TRUE

Answer 13

or
26>25
26<27

Answer 14

Check D for yourself and tell me if its a solution , as I actually think its not!

Answer 15

How would I check it?

Answer 16

ok you were given (4,33) so x=4 y=33

plug them in
33 > 6(4)+7 ; now tell me if that's true or not
33 < 6(4)+9 ; now tell me if that's true or not

Answer 17

still thinking...

Answer 18

sooooo
is 33 > 24+7 ?
is 33 < 24+9 ?

Answer 19

33>24+7

Answer 20

means is 33 bigger than 31

Answer 21

also is 33 less than 33

Answer 22

yes

Answer 23

ok so it gets past the first equation what about the second?

Answer 24

this question: 33 < 24+9 ?

Answer 25

means is 33 less than 33?

Answer 26

No it is equal

Answer 27

HA! so its false and is not a solution because they both have to be true :D

Answer 28

the question become
A
32 > -17 TRUE
32<-15 FALSE
B
26 > 25 TRUE
26 < 27 TRUE
C
25>25 FALSE
25<27 TRUE
D
33>31 TRUE
33<33 FALSE

The only one with two true statements is B

Answer 29

Ok thanks also are you abloe to help me on two step equations?

Answer 30

yep, post it and I will try to help

Answer 31

I have to work backwards like this... and plug in the numbers.

Answer 32

ok whats the equation?

Answer 33

i have to close this

Answer 34
