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

Actually Welcome to the concept of calculations of bills.

The bill calculation goes as equation,

y = $250 + n*($10)

here, n = number of lines,

1.) For n = 2 , Y = cost = 250 + 20 = $270

2.) for n = 4 , Y = $290

3.) for n = 6 , Y = $310

4.) for n = x, Y = $250 + x*($10)

for lastly 12 members we get as,

Y = 250 + (12)*(10) = 250+120 = $370

LekaFEV [45]
Hello there!

So, if this turtle is only going 2.5 miles per hour. This would mean that (EACH) hour, this turtle only arrived 2.5 miles. So, we do,

\boxed{10.0 \left \{ {{2.5+2.5=5.0} \atop {2.5+2.5=5.0}} \right.}

We would have to count how many ("2.5's" they are above.)

We count only 4.

I would take this turtle 4 miles to swim 10 kilometers.
