Hey! :)
10y-3(y+5)
Distribute the -3. 
-3*y= -3y  -3*5= -15
10y-3y-15
7y-15
"A" is the answer.

Answer:
<h2>It's not a function.</h2>
Step-by-step explanation:
A function is a process or a relation that associates each element x of a set X, to a single element y of another set Y.
We have:
{(3, -2), (1, 2), (-1, -4), (-1, 2)}
for x = -1 are two values of y = -4 and y = 2. Therefore this realtion is not a function.
 
        
                    
             
        
        
        
The answer is B. 120
nCr = n! / ((r! * (n - r)!)
n = 10
r = 3
10C3 = 10! / ((3! * (10 - 3)!)
         = 10! / ((3! * 7!)
         = (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
         = 3628800 / 30240
         = 120
        
             
        
        
        
Do you mean 6 to the 5th power. or is there another 6, if so then it would be 6 to the 6th power.
        
                    
             
        
        
        
Answer:
about 48.6%
Step-by-step explanation:
20 women's shoes are athletic.
35 women's shoes are formal.
52 women's shoes are casual.
The total number of women's shoes is 107.  So the probability that a randomly selected one is casual is:
P = 52/107
P ≈ 48.6%
