Inverse proportion is of the form:
y=k/x, in this case the variables are
z=k/x, and we are given the point (6,2) so we can solve for k
2=k/6
12=k, so our equation is:
z=12/x, so when x=13
z=12/13
        
             
        
        
        
16x³ - 54
= 2(8x³ - 27)
= 2(2x - 3)(4x² + 6x + 9)  ← answer
        
             
        
        
        
The answer would be 10 it is cheaper you must divide here is my work  
<span>You divide unit per price = 10/$6.75 = $1.48
12/$7.25 = $1.65
Which means 10 units are cheaper</span>
        
             
        
        
        
It's a trick question. There are an infinite number of mixed numbers between 3 and 4 that can multiply to equal 12 (for example, 3 and 3/7 times 3 and 1/2), but there are no mixed numbers between 3 and 4 that can multiply to equal 9. 3 times 3 is not between them but is 3, but that quantity is excluded because 3<x<4. Anything even a small bit above the number 3 would have to be multiplied by 2 and some fraction, which would not be between 3 and 4.
        
             
        
        
        
Answer:
Find below:
Step-by-step explanation:
To solve this, we either find the total cos5 of buying 40 bouquets at $2.50 or find the cost of one bouquet at $120.
Cost of one in pack of 40 at $120.
120 divided by 40 = $ 3
Now, we can see that $3>$2.50
This means that Kendra is wrong to buy the bouquet pack of 40 for $120
Hope this helps.
Good Luck
