Question

Tell me if I'm right !

Which of the following is not an equivalent form of the compound inequality

x + 15 less than or greater to 12 and x + 15 greater than or equal to 5


Answers :

12 greater than or equal to x + 15 greater than or equal to 5

−3 greater than or equal to x greater than or equal to −10

A number line with a closed circle on −10, a closed circle on −3, and shading in between.

A number line with a closed circle on −10, shading to the left, and a closed circle on −3, shading to the right.

Answer 1

I think the answer is the last one " A number line with a closed circle on −10, shading to the left, and a closed circle on −3, shading to the right. " am I right?

Answer 2

Answer 3

it'd be so much better if you'd just give us a picture :)

Answer 4

all this line close, divided by blue line and over and under with dots and so forth
hehe

Answer 5

You wrote:
"x + 15 less than or greater to 12 and x + 15 greater than or equal to 5"
Do you mean
"x + 15 less than or EQUAL to 12 and x + 15 greater than or equal to 5"?

Answer 6

yes I do sorry!

Answer 7

@jdoe0001 okay :)

Answer 8

x + 15 <= 12 and x + 15 >=5
Solve both inequalities:
x <= -3 and x >= -10

Answer 9

This means that x is greater than or equal to -10 and x is less than or equal to -3.
That means x is every number from -10 to -3, including -10 and -3.

Answer 10

so it would be shaded in between?

Answer 11

You are correct. The last choice is the incorrect answer to the compound inequality.

Answer 12

yes, the shading is in between.

Answer 13

so the answer is the last one right ?

Answer 14

@mathstudent55 So since it says NOT the answer will be the last one?

Answer 15

yes it should be that one..
