Answer 1

Help with Algebra 1 h.w??? PLZZZ HELP!!!!?
1.) A solution to the compound inequality 8 > 5 - 3x > -13 is provided below. Choose the statement that is true about the given solution.

8 > 5 - 3x and 5 - 3x > -13

Line 1

3 > -3x and -3x > -18

Line 2

-1< x and x < 6

Line 3


There is a mistake in line # 1.

There is a mistake in line # 2.

There is a mistake in line # 3.

There are no mistakes, the solution is correct.


2.) In Lake Mille Lax, a walleye (type of freshwater fish) must be less than or equal to 20 inches or longer than or equal to 28 inches for the fish to be considered a keeper. Choose the combined inequality that describes this scenario.

20 x 26

x 28

x 20 or x 28

none of the above

none of the above


3.) Solve -3x + 1 > 4 and describe the graph of the solution.

x < -1; Open circle on -1, shading to the left

x < -1; Open circle on -1, shading to the right

x > -1; Open circle on -1, shading to the left

x > -1; Open circle on -1, shading to the right


4.) Solve: 5(x + 6) 3x - 4

x -17

x 17

x -17

x -5


-2y - 7 > 11

5.) Part 1: Solve the inequality above.
Part 2: Describe the graph of the solution.



16 < 3x + 1 < 4

6.) Part 1: Solve the inequality above.
Part 2: Describe the graph of the solution.



Plzzz help thnx sooo much!!!

Answer 2

Select the inequality that corresponds to the given graph.

3x - 7 < 11

-4x > 24

-2x + 7 13

3(x - 2) - 3 x - 5

Answer 3

Please help I have taken this test online 3 times and still havent passed it and the lessons online dont help me... Please show your work if possible so I know what to do next time? :\ thanks

Answer 4

Wow, that's a lot in one shot. Did you miss everything listed?

Answer 5

yes it's 50 questions and these are the ones i dont get.

Answer 6

I don't see a mistake in number one... do you?

Answer 7

I wasnt sure about line 2... but i dont know...

Answer 8

It looks good to me, so I would say... no mistakes, solution correct.

Answer 9

Thanks!! :)

Answer 10

I don't see inequality signs in number 2... are they supposed to be there or is that exactly what you see on the test?

Answer 11

hmm... it should be:
A;<= and <=
b;<=
c;<= and >=
d;none of the above
these go in the blanks sorry about that :|

Answer 12

Basically the situation described is where fish of a certain size are making baby fish. They don't want you to kill those, you can go smaller or bigger.
x<=20 or x>=28. There is one answer that looks a little like this form, but the signs are missing.

Answer 13

Ohh Thanks so much! That makes sense now! :)

Answer 14

-3x+1>4 subtract 1 from both sides
-3x>3 divide both sides by -3, dividing by negative flips the sign
x<-1
open circle because of < without equal sign
shade to the left because all x's are smaller than one, all smaller numbers are to the left

Answer 15

Okay... I think I get that now Thanks so much for doing this :)

Answer 16

Is there a sign missing from number 4 between 5(x+6) and 3x-4 ?

Answer 17

hmm there should be a <= sign between 5(x+6) and 3x-4

Answer 18

sorry about that

Answer 19

No problem, this editorhas a limited font. Cutting and pasting can cause real problems if there are special characters like less than or equal to.

Answer 20

yeah I see that now haha :)

Answer 21

5(x+6) <=3x-4 distribute
5x+30<=3x-4 subtract 3x from both sides
2x+30<=-4 subtract 30 from both sides
2x<=-34 divide both sides by 2
x<=-17

Answer 22

Okay thanks so much!! :) you are a life saver!!

Answer 23

No problem, this is fun.
-2y-7>11 add 7 to both sides
-2y>18 divide both sides by -2, flip sign
y<-9
open circle at 9, shade to the left

Answer 24

Oh, I forgot to flip the sign :) It makes sense now! :)

Answer 25

Yes, when you multiply or divide by a negative.

Answer 26

Yeah I think that was part of my problem on some of them :)

Answer 27

16<3x+1<4 you don't have to split, but a previous problem did
16<3x+1 and 3x+1<4 subtract one from all sides
15<3x and 3x<3 divide by 3 on all sides
5<x and x<1 I see this as x is between 1 and 5... only works when signs are pointing in same direction... opposite directions usually means shade outside and leave a gap in the middle.
open dot at 1 and open dot at 5, shade between

Answer 28

Thank you, really :D

Answer 29

no problem, sorry that I was checking that guys joke and not helping.... hasta!

Answer 30

Haha you're fine :)

Answer 31

But thanks so much for helping me!!

Answer 32

Oh yeah, there was that graph of x<6

3x-7<11
3x<18
x<6 yeah, that one

Answer 33

Oh I forgot about that one but thanks!
