Question

Select the inequality that corresponds to the given graph.

Answer 1

5x + 7 >= 2 and 10x <= 30

6x + 7 >= 25 or 2x - 8 < -4

4x + 10 <= 6 or 5x - 6 >= 14

37 <= 8x - 3 >= 61

Answer 2

Is it meant to be the blue or yellow portion?

Answer 3

the blue

Answer 4

Well, you can test them individually.

5x + 7 >= 2

we replace x with -2 and find -3 >= 2 which is obviously false


6x + 7 >= 25

same thing, replacing x with -2 we get -5 >= 25, false as well

4x + 10 <= 6

x = -2 this gives us 2 <= 6 which is true!

now with x = 6, this gives us 34 <= 6 which is false

and so on.

Answer 5

Try and derive an inequality from the picture and see if it matches any listed

Answer 6

so C?

Answer 7

No, as it only applies to the negative portion of the graph

Answer 8

srry i just dont get it

Answer 9

Ok look at first set A:
solve each seperately as you normally do

Answer 10

ok

Answer 11

the idea is to draw both set of solutions on one graph...

5x + 7 >= 2
thus
x>=-1

10x <= 30
x<= 3

this is not true for your graph!!! so not A

Answer 12

5x + 7 >= 2 and 10x <= 30
-7 -7
5x >= -5
5 5
x >= -1

Answer 13

forgot the rest :PPP

Answer 14

ok

Answer 15

the word and in between means it must be true for both, like overlap!! Go towards each other...

Answer 16

It cant be B right because its just the < sign

Answer 17

Now look at B:
6x + 7 >= 25 or 2x - 8 < -4
6x >= 25-7 2x < -4+8
6x>=18 2x<4
x>= 6 x<2
which is also not true for your graph! As

Answer 18

when drawing both solutions on the same graph it doesn't look the same as your graph!

Answer 19

Thus not B either

Answer 20

4x + 10 <= 6 or 5x - 6 >= 14
-10 -10 +6 +6
4x <= -4 5x >= 20
4 4 5 5
x <= -1 x >= 4

Answer 21

so its C right????

Answer 22

YES C as the word or means there is a gap between the two lines (the yellow section...) the word and means the two blue lines should meet up or join...

Long story short. C

Answer 23

thank you so much for the help

Answer 24

Pleasure!
