In this experiment, there is an independent variable that is the time spent playing video games.
<h3>What is an independent variable?</h3>
In research there are different ways to test a hypothesis. One of them is the experiments in which we have one or more factors that can be modified to alter the result.
These factors are known as independent variables because their variation does not depend on other factors. On the contrary, they influence the variation of other factors that are known as dependent variables.
According to the above, it can be inferred that time is the independent variable of this research because its modification is planned to evaluate the different variables that it can cause.

Answer:
(-3, 8)
Step-by-step explanation:
For m the midpoint of xy, we have ...
m = (x+y)/2 ⇒ y = 2m-x
y = 2(4, 3) -(11, -2) = (2·4 -11, 2·3 +2)
y = (-3, 8)
Infinite solutions for this
B) 5(x-6)
you factor out 5 for each term
The first one is the square root of 9 and 16
