Answer:
x>-6, x<-4
Step-by-step explanation:
|x+5|>-1
x+5>−1 (Possibility 1)
x+5−5>−1−5 (Subtract 5 from both sides)
x>−6
x+5<−(−1)(Possibility 2)
x+5<1(Simplify both sides of the inequality)
x+5−5<1−5(Subtract 5 from both sides)
x<−4
x>-6 or x<-4
 
        
             
        
        
        
Answer: 8/25
Step-by-step explanation: Using the place value chart, we can see that the decimal 0.32 is thirty-two hundredths so we can write 0.32 as 32/100.
Since 32/100 is not in lowest terms, we divide both the numerator and the denominator by 4 and we get the equivalent fraction 8/25.
This means that 0.32 can be written as the fraction 8/25 which is in lowest terms.
 
        
             
        
        
        
Part 1We are given 

. This can be rewritten as 

.
Therefore, a=1, b=-18, c=0.
Using the quadratic formula     
 
     
The values of x are     
 
      Part 2
Part 2Since the values of y change drastically for every equal interval of x, the function cannot be linear. Therefore, the kind of function that best suits the given pairs is a 
quadratic function. Part 3.The first equation is 

.
The second equation is 

.
We have      
 
     
Factoring, we have      

Equating both factors to zero.     
 
     
When the value of x is 6, the value of y is      

When the value of x is -3, the value of y is      

Therefore, the solutions are (6,38) or (-3,11)
 
        
             
        
        
        
Answer:
1.B not sure about 2 though sorry i couldnt help u on 2 Step-by-step explanation:
 
        
             
        
        
        
Here is how I completed the problem:
I started by creating a ratio:

<em>Where 'x' is the desired amount of the 18% solution of sulfuric acid. 
</em>From here, I solved for 'x':
<em>
</em>







∴You will need to add 1080ml of 18% Sulfuric Acid in order to obtain a 15% solution.
