Answer:

option A, D and F are correct.

|x| = 9,  -|-x| = –9 and |–x| = 9

Step-by-step explanation:

Absolute value of any number is positive or 0.

for example:

|-a| = a

|a| = a

As per the statement :

For which equations is x = 9 a possible solution.

Option A:

|x| = 9

by definition of absolute value:

⇒x = 9

Similarly,

Option B:

-|x| = 9

⇒ -x = 9 or x = -9

Option C

-|-x| = 9

⇒ -x = 9

⇒x = -9

Option D:

-|-x| = –9

⇒ -x = -9

⇒ x = 9

Option E

|x| = –9

⇒x = -9

Option F

|–x| = 9

⇒x =9

Option G

|–x| = –9

⇒x = -9

Therefore, an equation for which possible solution is x = 9 are:

|x| = 9,  -|-x| = –9 and |–x| = 9.

Given the graph below, which of the following statements is true?
nirvana33 [79]

Answer:

D) The graph does not represent a one-to-one function because the y-values between 0 to 2 are paired with multiple x-values.

Step-by-step explanation:

Let's find the ordered pairs.

(-4, 4), (-3, 2), (-2, 0), (-1, 0.5), (0, 1), (1, 1.5), (2, 2), (3, 0)

The graph passed through above points.

In the x-coordinates -3, 2 gives the same output. Therefore, the given function is not one-to-one.

Therefore, the answer D)

The graph does not represent a one-to-one function because the y-values between 0 to 2 are paired with multiple x-values.

Hope you will understand the concept.

Thank you.
