Question

Which of the following is not a way to represent the solution of the inequality 8x - (5x + 4) greater than or equal to -31?

Answer 1

need help please.

Answer 2

Where's the answer choices?

Answer 3

x greater than or equal to -9

-9 less than or greater to x

A number line with a closed circle on -9 and shading to the left

A number line with a closed circle on -9 and shading to the right

Answer 4

8x - (5x + 4) >= -31
8x - 5x - 4 >= - 31
3x >= -31 + 4
3x >= - 27
x >= - 9 or -9 < = x

number line with a closed circle on -9 (because if it has an equal sign, it has a closed circle) and it is shaded to the right (because it is greater then).

so what do you think the answer is ?

Answer 5

d

Answer 6

no...try again

Answer 7

c

Answer 8

yep..that one is not true. Because the shading will go to the right, not the left

Answer 9

oh i see i have one more it similar to it if you don't mind.

Answer 10

I don't mind

Answer 11

Choose the correct description of the graph of the compound inequality

3x + 2 > 2 and 3x less than or greater to 6.

Answer 12

is that supposed to be less then or equal ?

Answer 13

then the answer:

A number line with an open circle on 0, shading to the left, and a closed circle on 2, shading to the right

A number line with a closed circle on 0, shading to the left, and an open circle on 2, shading to the right

A number line with a closed circle on 0, an open circle on 2, and shading in between

A number line with an open circle on 0, a closed circle on 2, and shading in between

Answer 14

less then

Answer 15

3x + 2 > 2
3x > 2 - 2
3x > 0
x > 0

3x <= 6
x <= 2

open circle on 0, closed circle on 2, shading in between

Answer 16

remember this..
open circle if there is no equal sign
closed circle if there is an equal sign
< less then means shading to the left
> greater then means shading to the right

Answer 17

so it would be D

Answer 18

yep...its D
