Question

10 < –3x + 1

Answer 1

9<-3x
3>-x
x>-3 , correct me

Answer 2

It's dividing by a negative that changes the sign.

2>-3

-2<3

Answer 3

i think m correct then

Answer 4

You changed the sign when you divided by 3, which is wrong.

Answer 5

oh

Answer 6

Small mistake, you still got the right answer. But anytime you multiply or divide both sides of an inequality by a negative number you have to swap the sign too.

Answer 7

i'm confused

Answer 8

check out ma answer, thats final

Answer 9

10 < -3 x + 1
Would I start by adding three to the -3 and the 1?

Answer 10

Start by subtracting 1 from either sides

Answer 11

10-1<-3x+1-1
9<-3x
3>-x
-3<
x

Answer 12

@ambermarie , What do you get?

Answer 13

-3<x

Answer 14

10 < -3 x + 1
-1 -1?

Answer 15

10 < -3x + 1
Do one step at a time. You started it correctly.
First, subtract 1 from both sides:
9 < -3x you did this correctly
Now since x is being multiplied by -3, you need to divide both sides by -3.
Since you're dividing both sides of an inequality by a negative number, this is
where the inequality sign changes direction.
9/(-3) > (-3x)/(-3)
-3 > x
x < -3

Answer 16

10 < -3x + 1
10 - 1 < - 3x + 1 - 1
9 < - 3x (when you divide by a negative change the sign.)
-3 > x

Answer 17

No no no! -- 10 -1 < -3x +1 -1

Answer 18

Okay,

Answer 19

9< -3x?

Answer 20

Perfect :)

now, to simplify the inequality, divide both the sides by (-3)

here, we have to be "very careful" about one thing.

Whenever, you divide an inequality by a negative number, the inequality sign changes.

So, what do you get now ?

Answer 21

9 < -3x
/-3 /-3
9/-3= -3
-3>x

Answer 22

Wow :D
