An individual closes out help desk tickets at a rate of 4 tickets per hour for h hours. Write an equation that expresses the situation, let x be the independent variable and y be the dependent variable.

y = 4x

Step-by-step explanation:

An independent variable is the variable that is changed or controlled in an experiment or observation to test the effects on the dependent variable.  

A dependent variable is the variable being tested and measured in a scientific experiment.  

The dependent variable is 'dependent' on the independent variable.

In this case, the number of help desk tickets closed out is dependent on the number of hours the individual works so y is the number of tickets closed (dependent variable) and x is the number of hours worked (independent variable). The number of tickets closed off will be 4 multiplied by the number of hours worked i.e. y = 4x

step-by-step explanation:

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
