Hi!
You didn't list the options, but I think I know the answer. Let me know if my answer isn't listed! :)
 We need to multiply the exponents.
We need to multiply the exponents.3 · -5 = -15
The answer is 
Hope this helps! :)
 
        
        
        
Let x be the number of treats bought 
Let y be the pounds of food bought 
25= 2y+x 
Given that she has buys 9 pounds of dog food: 
25= 2(9)+x 
25=18 +x 
25-18 =x 
7=x 
With the money she has left over, she can buy 7 treats. 
Hope I helped :)
        
             
        
        
        
Answer:
Step-by-step explanation:
A parallel line will have the same slope as the reference line.  In this case, I don't see the "given line" as promised in the question.  If it does appear, and it looks like y = 5x + 3, for example, the slope is 5 and the new line will have the same slope.
<h3>
<u>If this slope is correct</u>, we can start the equation for the parallel line that goes through point (-3,2) by starting with:</h3><h3 /><h3>y = 5x + b</h3><h3 /><h3>We need a value of b that forces the line to go through point (-3,2).  We can do that by using the given point in the equation and solving for b:</h3><h3>y = 5x + b</h3><h3>2 = 5(-3) + b</h3><h3>b = 17</h3><h3 /><h3>The parallel line to y=5x+3 is</h3><h3>y = 5x + 17</h3><h3 /><h3>See attachment.</h3><h3 /><h3 /><h3 />
 
        
             
        
        
        
A. I’m not sure what this is asking but I’d guess 8,9,10
B is 19,20,21
C is there is none
        
                    
             
        
        
        
Answer:
k = 5
Step-by-step explanation:
y = kx
10 = 2k
k = 5
