Answer: 
Step-by-step explanation:
By definition, Direct proportion equations have the following form:

Where "k" is the constant of proportionality.
In this case you know that the distance (in meters) that an ant can travel varies directly with the amount of time (in hours) the ant spends walking.
With this information you can write the following equation:

According to the exercise, the constant of proportionality is:

Therefore, substituting the value of the constant of proportionality into the equation, you get that the equation that represents the proportional relationship between "d" and "t" is:

Answer:

Answer:
<h2>( 6 , 7 )</h2>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula

From the question we have

We have the final answer as
<h3>( 6 , 7 )</h3>
Hope this helps you
Simplifying this, we get:
(x+4)(x-4) = 0
Now, to get 0, we can replace x for one of these things to make 0, so:
x can either be 4, or -4
