The solution to |x+8|=1 is  -7,-9

Explanation:

Given :

|x+8|=1

To Find:

The solution to |x+8|=1

Solution:

Now, we know the Properties of modulus function as  

|x|  = x          if x>0

|x|= -x           if x<0

Similarly property will be followed in the given question as

Case 1:  if x>-8  

Then the given equation will become as  

|x+8|= x+8=1

After solving the equation , we will get

x= -7

Similarly,  

Case2: if x<-8

Then the given equation will become as  

|x+8|= -(x+8)=1

After solving the equation , we will get  

x= -9

Hence,  the possible values of x are -7,-9

Step-by-step explanation:

8-7 in the inside

Absolute value of 1 is 1

OR

8-9 in the inside for -1

Absolute value of -1 is 1

Absolute value signs makes everything positive

Human blood has an approximate pH of 7.3. Which substance is more basic than human blood?
ratelena [41]


so, 7 is neutral anything past 7 is considered basic.

answer: <em>a water and ammonia solution with a pH of 11 (very basic).</em>

<em />any number under 7 is acidic and of course there are different degrees of acidic just like there are different degrees of basicity.   

______________________________________________________________

- stomach's digestive juices, would be considered very acidic

-apple juice is also acidic but not as acidic  like stomach juices.

- grape juice, is becoming less acidic.

Hopefully this helped and good luck.

Answer:

  1. 13 ft
  2. (a) 1 second; (b) t = 0, t = 1/2

Step-by-step explanation:

<h3>1. </h3>

Let w represent the length of the wire. Then the height of attachment is (w-1). The Pythagorean theorem tells us a relevant relation is ...

  5² +(w -1)² = w²

  w² -2w +26 = w² . . . . . . . eliminate parentheses, collect terms

  26 = 2w . . . . . . . . . . . . add 2w

  13 = w . . . . . . . . . . . . divide by 2

The length of the wire is 13 feet.

__

<h3>2. </h3>

(a) When h = 0, the equation is ...

  0 = -16t^2 +8t +8

Dividing by -8 puts this into standard form:

  2t^2 -t -1 = 0

Factoring, we get ...

  (2t +1)(t -1) = 0

The positive value of t that makes a factor zero is t = 1.

It will take 1 second for the gymnast to reach the ground.

__

(b) When h = 8, the equation is ...

  8 = -16t^2 +8t +8

Subtract 8 and divide by 8 to get ...

  0 = -2t^2 +t

  0 = t(1 -2t) . . . . factor out t

Values of t that make the factors zero are ...

  t = 0

  t = 1/2

The gymnast will be 8 feet above the ground at the start of the dismount, and 1/2 second later.
