Hi yes what do u need help with??
It is just the difference between the signs
The life expectancies of residents of a country for which the average annual income is $80,000 for the three models are 12309.9352, 172.2436 and 4828.1393
The life expectancies of the models are given as:
--- model 1
--- model 2
--- model 3
Given that the average annual income is $80,000;
We simply substitute 80000 for income in the equations of the three models.
So, we have:
<u>Model 1</u>



<u>Model 2</u>



<u>Model 3</u>



Hence, the life expectancies are 12309.9352, 172.2436 and 4828.1393

Answer:
x = -1
y = 1
Step-by-step explanation:
<u><em>Since it gives you "y", plug in the number given into the equation:</em></u>
y = -6x - 5
1 = -6x - 5
<u><em>Then, add 5 to both sides:</em></u>
1 = -6x - 5
+5 + 5
________
6 = -6x
<em><u>Divide both sides by -6:</u></em>
6 = -6x
-1 = x
So now you have, x = -1 and y = 1
