D because  each y value is obtained by multiplying  x by -2
y = -2x  which is direct variation.

Answer:
The ratio that exist between this three elements are 25 : 19 : 13. 
Step-by-step explanation:
Ratio compares one thing to another. Ratios indicate the comparison of the size of a number to another . One trick about ratio is that you can multiply or divide the ratios by same number. For example the ratio of boy to girls can be represented as 3 : 4. If you multiply the ratios by 2 you will get the ratio 6 : 8 and it still represent the same ratios of boys to girls. Ratios can be written as a fraction for example 3/4 for our example. 
The cost of the unit is made up of $6.25 , $4.75 and $3.25. 
$6.25  $4.75  $3.25 . Let us multiply by 100 to remove the decimals.
625 : 475 : 325 . Now let simplify the ratios by dividing through by 25. 
625/25 : 475/25 : 325/25 . The simplest ratios can be written as follows
The ratios are 25 : 19 : 13. 
 
        
             
        
        
        
Answer: 2 decimal digits
Step-by-step explanation:
When multiplying decimals, placement of the decimal point is very important. Since there is one decimal digit in each factor, there must be two decimal digits in the product. This is because tenths x tenths = hundredths
Hope this helps and good luck! :)
