Answer:
<h2>-4</h2>
Step-by-step explanation:
Given the function f(x)=(x+4)², <u>the x intercept occurs at f(x)  = 0,</u> substituting f(x) = 0 into the given equation to get the value of x we have;

Taking the square root of both sides 

Subtracting 4 from both sides of the equation

Therefore the x intercept of the equation is -4
 
        
             
        
        
        

notice, it was pawned for only 1 month, so the "yearly" rate is for 1 month, which is 1/12 of the year, since a year has 12 moths
you'll get a rate in decimal terms, to get the % amount, just multiply it times 100
 
        
             
        
        
        
Answer:
P (black marble) =3/11
Step-by-step explanation:
We need to find the total number of marbles
4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles
We take away a black marble and throw it away
3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles
The probability of drawing a black marble is 
P (black marble) = black/total
                            =3/11
