Question

i need help with algebra? help please? someone?

Answer 1

We don't need your desperate pleas. We need questions to help you with.

Answer 2

im sorry, its just im very stressed with algebra. and i am very confused. this is the question

Choose the correct description of the graph of the compound inequality

x - 1 alt= 9 or 2x alt= 24. (5 points)

A number line with an open circle on 10, shading to the left, and an open circle on 12, shading to the right.
A number line with an open circle on 10, an open circle on 12, and shading in between.
A number line with a closed circle on 10, a closed circle on 12, and shading in between.
A number line with a closed circle on 10, shading to the left, and a closed circle on 12, shading to the right.

Answer 3

Answer 4

What's alt? o-o

Answer 5

huh? its a question with 4 answers to choose from im very confused i don't get it. i go to online school @Grazes

Answer 6

x - 1 alt= 9 or 2x alt= 24.
Does it say alt in the problem or is it a copying error? If it is the former I have no clue.

Answer 7

If it's an inequality it seems like it should be >= or <= or something.

Answer 8

I would assume that they are inequality signs that didn't copy over.

Answer 9

its a greater than sign with a line under.

Answer 10

for which one?

Answer 11

Ok, that means greater than or equal, or >= if you can't type \(\ge\)

Answer 12

sorry its this x - 1 <= 9 or 2x >= 24

Answer 13

Ok. First of all, you're using closed circles, because that's what the "or equal to" means. An open circle means that value isn't included, like if it's just greater than or just less than.

Answer 14

So what you want to do is solve for x in both cases.
x-1<=9 --> x<=10
2x>=24 --> x>=24
You can graph these on a number line. Because it says or, you do not need to find the intersection of these two sets(the place where they over lap), you need to find the union.
The other thing is that you use the open circle when you have a non-inclusive inequality like > or <. You would use the closed circle when you have something inclusive like >= or <=.
If you graph it correctly, it would be:
"A number line with a closed circle on 10, shading to the left, and a closed circle on 12, shading to the right."

Answer 15

You can then just solve each one for x like it was an equation and you'll get two expressions. And, ninja'd so do that.

Answer 16

I type slowly :P

Answer 17

thank you, i understand it much better now :D
