The population of DeSoto rose an average of 142 people for each of 5
years. It then had 5,428 people. Assume
the relationship is linear. Find and
interpret the rate of change
and the
initial value.

Please check explanations

Step-by-step explanation:

Here, we want to make an interpretation

From the question, we have that initially when the count was started, there were 5,428 people; this means that the initial value of the data is 5,428

For the rate of change, we have that there is an average increase of 142 people for each of 5 years;

That means per 5 years, there is an increase of 142 people and this is what represents the rate of change

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
