The number of links in a chain and the length of the chain are related. Identify the dependent variable in this relationship. What is the dependent variable?

The number of links in a chain

Step-by-step explanation:

An independent variable is any variable whose value or identity does not in any way affect the event of another variable in the system. A dependent variable is a variable whose value or identity depends on one or more variables in the system.

From the information given:

The length of the chain is an independent variable while the number of links that depends on the length of the chain is the dependent variable.

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
