Answer:
B.
Step-by-step explanation:
When the number is positive and not inside the parentheses it means it gets translated up.
Answer: -1410
Step-by-step explanation:
Let's start by subbing in -4 for x

Now we can solve

Answer:
20,158 cases
Step-by-step explanation:
Let
represent year 2010.
We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.
Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.
We can represent this information in an exponential decay function as:


To find number of cases in 2020, we will substitute
in our decay function as:



Therefore, 20,158 cases will be reported in 2020.
Hi!
<h3>Use the distribution property</h3>
1.4t — 0.4 * t - 0.4 * —3.1 = 5.8
1.4t — 0.4t - 1.24 = 5.8
<h3>Simplify</h3>
1t - 1.24 = 5.8
<h3>Add 1.24 to both sides</h3>
1t - 1.24 + 1.24 = 5.8 + 1.24
1t = 7.04
<u>t = 7.04</u>
<h2>The answer is t = 7.04</h2>
Hope this helps! :)
