Question

|3x-9|>0

Answer 1

\[(x+3)^2(2-x)\div(x+4)(x^2-4)\le0\]

Answer 2

Is this two separate questions?

Answer 3

yes

Answer 4

On the first one, is there supposed to be a "|" in the beginning or is that a mistake?

Answer 5

typo...just corrected :)

Answer 6

for the first one i know the answer is: \[(-\infty,3)u(3,\infty) but i don't know how \to get that\]

Answer 7

What are the instructions?

Answer 8

it says to find the solution of the equation

Answer 9

This is for the first one:

|3x-9|>0

Remove the absolute value term. This creates a \ on the right-hand side of the equation because |x|=+-x.
3x-9>+-(0)

Set up the portion of the +- solution.
3x-9>0

Since -9 does not contain the variable to solve for, move it to the right-hand side of the inequality by adding 9 to both sides.
3x>9

Divide each term in the inequality by 3.
x>3

Set up the - portion of the +- solution. When solving the - portion of an inequality, flip the direction of the inequality sign.
3x-9<-(0)

Multiply -1 by the 0 inside the parentheses.
3x-9<0

Since -9 does not contain the variable to solve for, move it to the right-hand side of the inequality by adding 9 to both sides.
3x<9

Divide each term in the inequality by 3.
(3x)/(3)<(9)/(3)

Simplify the left-hand side of the inequality by canceling the common terms.
x<(9)/(3)

Simplify the right-hand side of the inequality by simplifying each term.
x<3

The solution to the inequality includes both the positive and negative versions of the absolute value.
x>3 or x<3

Hope this helps. I don't know how you got your answer but I think it is incorrect.

Answer 10

my professor gave us the answers and we have to solve them.... thank you whoever you are!!!

Answer 11

What was the solution to the second one?

Answer 12

\[(-\infty,-4)u{-3}u(-2,2)u(2,\infty)\]

Answer 13

\[5-\sqrt{-121}\div1+\sqrt{-25}\]

Answer 14

I'm sorry, could you take a pic maybe because when the divide sign is used, I don't know what is over what. It gets very confusing and I may give you a wrong answer. I don't want to do that. Does the second one look like this?
