Question

can anyone help me? @sheelo_mughal @texaschic101 @YanaSidlinskiy @mathmale @ankitshaw

Answer 1

I can!

Answer 2

for what just type ur ques.

Answer 3

Solve the inequality 2x + 8 < 5x - 4. I will show you what i got so far

Answer 4

This is what i got, anyone else agree?
2x+8<5x-4
10x2<x-4
5x<4
x>4

Answer 5

I got x<4 what did i do wrong?

Answer 6

You didn't reverse the sign at the end of the problem

Answer 7

You kept it like this <, But you were suppose to change it to this >

Answer 8

why?

Answer 9

2x + 8 < 5x - 4
2x - 5x < -4 - 8
-3x < - 12 -- when dividing/multiplying by a negative, the sign changes
x > 4

Answer 10

@texaschic101 Bingo!

Answer 11

4x-2x-2=3x+10

2x-2=3x+10

2x-3x=10+2

-x = 12

x= -12 This was next problem

Answer 12

correct

Answer 13

Your correct!

Answer 14

Compare and Contrast: Below are two equations. Solve each equation and compare the two solutions. Choose the statement that is true about each solution.
Equation #1 Equation #2
6 - x = 5x + 30 4x - 8 = 3x + 2

The solution to equation #1 is smaller than the solution to equation #2.

The solution to equation #1 is larger than the solution to equation #2.

The solution to equation #1 is the same as the solution to equation #2.

None of the statements above describe solutions to equations shown.

Answer 15

this one i dont understand at all

Answer 16

i was thinking A but im not 100% sure

Answer 17

6 - x = 5x + 30
-x - 5x = 30 - 6
-6x = 24
x = -4

4x - 8 = 3x + 2
4x - 3x = 2 + 8
x = 10

solution to equation 1 is smaller then equation 2

Answer 18

Man! You beat me to it! @texaschic101

Answer 19

lol....sorry. I didn't mean to take over your question

Answer 20

I know it seems like i dont need help because so far everything has been pretty much correct but i like to make sure the work i do is 100% correct. So thank you both.

Answer 21

Lol, its cool

Answer 22

Anytime! @jadee27p

Answer 23

jadee...confirmation is always good.

Answer 24

I have 2 more. Solve for x: -3|x - 3| = -6

x = 1, x = -1

x = 1, x = 5

x = 0, x = 5

No solutions

Answer 25

Compare and Contrast: Below are two equations. Solve each equation and compare the two solutions. Choose the statement that is true about each solution.

Equation #1


Equation #2

-5|3x - 2| = -15


|2x - 9| = 11

Equation #1 and Equation #2 have the same number of solutions.

Equation #1 has more solutions than equation #2.

Equation #1 has fewer solutions than equation #2.

None of the statements above describe the number of solutions to equations shown.

Answer 26

and that's all.

Answer 27

-5|3x - 2| = -15 has two solutions= -1/3 and 5/3
|2x - 9| = 11= Also has two solutions= -1 and 10

Answer 28

Therefore i would go with, [Equation #1 and Equation #2 have the same number of solutions.]

Answer 29

Solve for x: -3|x - 3| = -6
x = 1,
x = -1 x = 1
x = 5 x = 0
x = 5 No solutions What about this one

Answer 30

Are they your answer choices or the answer you got?

Answer 31

Choices

Answer 32

Okay :)

Answer 33

-3 | x - 3| = -6 --- divide both sides by -3
| x - 3 | = 2

x - 3 = 2 -(x - 3) = 2
x = 2 + 3 -x + 3 = 2
x = 5 -x = 2 - 3
-x = -1
x = 1

xolutions are : x = 5 and x = 1

um...I am getting this

Answer 34

For that one i would go with
x=1 and/or x=5

Answer 35

In order for solving problems like this what would i start off with ?

Answer 36

get just what is in the absolute value on one side, and everything else on the other side

Answer 37

Thank you guys :)

Answer 38

anytime :)

Answer 39

No problem!
