Please i need help please help me out!
TiliK225 [7]

Answer:

1. 13 or -13

2. -5 < y < -3

3. 6 or -6

4. 1/8 or -1/8

Step-by-step explanation:

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |x|

 For the Negative case we'll use -(x) 

For the Positive case we'll use (x) 

Step  3  :

Solve the Negative Case

      -(x) = 13 

     Multiply

      -x = 13 

     Multiply both sides by (-1)

      x = -13 

     Which is the solution for the Negative Case

Step  4  :

Solve the Positive Case

      (x) = 13 

     Which is the solution for the Positive Case

Step  5  :

Wrap up the solution

 x=-13

 x=13

But for the case of question (2) its a different pattern..

Since this is a "less than" absolute-value inequality, my first step is to clear the absolute value according to the "less than" pattern. Then I'll solve the linear inequality.

| y + 4 | < 1

–1 < y + 4 < 1

This is the pattern for "less than". Continuing, I'll subtract 3 from all three "sides" of the inequality:

–1 – 4 < y + 4 - 4 < 1 – 4

–5 < y < -3

- 5 < y <  - 3

The solution to the original absolute-value inequality, | y + 4 | <  1 , is the interval:

- 5 < y  <  - 3

Help with functions, i only need help with #2
olasank [31]
Let's look at the first one, then you can practice the rest on your own. So, h(0) = - 2 because the number in h() is which number you search for on the bottom row. Then you look at the number above that bottom number, which, in this case is - 2, and that number is your answer.

Is 14,48,50 a Pythagorean triplet <br> Step by step explanation please
Svetlanka [38]

Answer:

yes

Step-by-step explanation:

If the values are a Pythagorean triplet then the square of the largest value should equal the sum of the squares of the other 2

largest value = 50 ⇒ 50² = 2500

14² + 48² = 196 + 2304 = 2500

Since 50² = 14² + 48² then 14, 48, 50 are a Pythagorean triplet
