Answer:
I am pretty sure that the answer is 18+2n
Answer:
A: y < -2x - 1
Step-by-step explanation:
First, to figure out which part of the graph to be looking at, you will look at the shaded region as the solution area.
So, the solution area is to the left of the line. Said line is a dotted line which means that the points on the line can not be a solution.
If the points on the line can not be a solution then it eliminates answer choices C and D because y can not equal the other side of the inequality.
Now, we will bring the shaded region back into focus to find out if y is greater than or less than the other side. The shaded area is "below" the line so it is less than -2x - 1.
To ensure this is correct, plug two points into the inequality we just chose, one from the shaded region and one not, just to make sure the answer is correct.
I picked (-3,4) to test. So plug them into the inequality to get:
4 < -2 (-3) - 1
So 4 < 6 - 1 which is correct.
Then from the other side of the line I picked (5,2)
2 < -2 (5) - 1
2 < -10 - 1
2 < -11 is not true so the inequality that we found was correct.
Answer:

I need to draw a picture to explain.
Answer:
L = 80.2 + 2(0.4)
(b) No, one linear equation will be sufficient to solve the problem. Because it is not two statements of equation
Step-by-step explanation:
Between 1996 and 2005, there is 10 years difference.
It is given in the question that the life expectancy increases by 0.4 every five years.
Between 1996 and 2005, life expectancy of woman born will increase by 2x0.4 = 0.8.,
In 2005, the life expectancy of woman born is:
L = 80.2 + 0.8 = 81.0 years
