Question

Draw a graph that represents the solution set for the compound inequality shown below? −2x − 15 ≥ 3x or x − 3 > 5

Answer 1

how about you try and solve it first, and show us what you got? then we can help out.

Answer 2

I try to learn by what you guys give me because I don't understand how to it. :l

Answer 3

Now, you know how to solve for x; so, do that and show us what you come up with.

Answer 4

Alrighty, wait.

Answer 5

Yes, find the interval for x, just like the previous question.

Answer 6

I ended up with \[-3 \le X \] or x > 8

Answer 7

I am not sure how you got −3≤X, do you want to go over that?

Answer 8

well i moved the -2x positive to the 3x and then it gave me -15≤5x, I divided and I got -3≤x

Answer 9

−2x − 15 ≥ 3x

-15 ≥ 5x

-3 ≥ x

Answer 10

what do you think of that?

Answer 11

But isn't the sign supposed to change when you divide?

Answer 12

ONLY when you divide by a NEGATIVE number!

Answer 13

;) that is the trick

Answer 14

NO WONDERRRRRRR omg I'd always get them wrong, thank you. o:)

Answer 15

ok so now, -3 ≥ x OR x>8

Answer 16

do you know how to graph that, I think you are supposed to graph it on a line?
