please help me fan and medal

Solve for x: -3|x - 3| = -6 x = 1, x = -1 x = 1, x = 5 x = 0, x = 5 No solutions

Okay since x-3 is an absolute value, it means the number can be a positive or a negative as long as the difference is the same value. What multiplied -3 = -6?

OpenStudy (josedavid):

@Nnesha @nincompoop @nobrainiachere

OpenStudy (josedavid):

what u mean

OpenStudy (anonymous):

An absolute value is the number of spaces from the integer to 0, so basically you remove the negative. Like if you have |-2|, it's the same as just saying 2.

OpenStudy (anonymous):

To simplify the equation a bit use this: |x - 3| = 2 what two numbers could you use for x now?

OpenStudy (josedavid):

5

OpenStudy (anonymous):

And what else?

OpenStudy (josedavid):

ummm

OpenStudy (anonymous):

If |2| = 2 and |-2| = 2, then what would be the second x?

OpenStudy (josedavid):

1

OpenStudy (anonymous):

Yes! So which answer choice has both x = 5 and x = 1?

OpenStudy (josedavid):

b

OpenStudy (anonymous):

Yep. :) Do you understand it a bit more or do you still need help?

OpenStudy (josedavid):

thank u so much

OpenStudy (anonymous):

No problem. :)

OpenStudy (josedavid):

Choose the correct description of the graph of the compound inequality: x - 3 < -9 or x + 5 greater than or equal to 12 A number line with a closed circle on -6, shading to the left, and an open circle on 7, shading to the right A number line with an open circle on -6, a closed circle on 7, and shading in between A number line with an open circle on -6, shading to the left, and a closed circle on 7, shading to the right A number line with a closed circle on -6, an open circle on 7, and shading in between

OpenStudy (josedavid):

@danniisnotcool

OpenStudy (anonymous):

Okay, think of the two inequalities as equations, x - 3 = 9 x + 5 = 12 Solve for x on both then put the original sign back in.

OpenStudy (anonymous):

@josedavid

OpenStudy (josedavid):

sorry about that

OpenStudy (josedavid):

yes

OpenStudy (anonymous):

Look at what I said above the mention

OpenStudy (josedavid):

A=12 B=17

OpenStudy (josedavid):

u there

OpenStudy (josedavid):

@danniisnotcool

OpenStudy (anonymous):

Yes, sorry was doing homework myself. So which kind of circle would < get on a number line?

OpenStudy (josedavid):

cool no rush

OpenStudy (josedavid):

what u mean

OpenStudy (josedavid):

is the first one

OpenStudy (anonymous):

Would the point on a number line be a filled in circle or an open circle for a <?

OpenStudy (josedavid):

is c is hard

OpenStudy (anonymous):

Oh, and for the second equation, it's x is greater than or equal to 7, not 17.

OpenStudy (anonymous):

But yes, the answer is c.

OpenStudy (josedavid):

thank u so much thank u

OpenStudy (josedavid):

u are the best i need to go bye take care

OpenStudy (josedavid):

i got it right
