2. The number of people in a
town n years after the initial
count can be modeled by
the equation p(n)=25,000(0.8)n
where P is the population
and n is the number of years.
b. Is this town growing or
shrinking in population?
By what percentage?
a. What was the population
at the initial count?
c. Write an expression to
predict what the population
will be in 5 years
Answers
Answer:
Step-by-step explanation:
25,000*0.8*n
25,000* 0.8= 20,000n
Therefore if the value of n is any number below 1 (including) then the population will decrease
If the value of n is any number above 1 (not including 1 specifically above 1.25 to show increase because 1.25* 20,000= 25,000) then it will show an increase with 1 it will just be 20,000 that being less then 25,000.
Answer:
-Population at the initial count: 25,000
-Is it increasing or decreasing: It depends on the value of n (explained above)
-By what percent: 80%
-Expression for 5 years: 25,000*0.8*5
- 25,000*0.8*5= 100,000 people

Solve 7(y + 2) – (4y – 10) = 44 – 2y + 5
A.y = -5
B.y = 5
C.y = -10
Answers
Answer:
y = 5
Step-by-step explanation:
7(y + 2) – (4y – 10) = 44 – 2y + 5
(7y+14) - (4y - 10) = 49 -2y
3y +24 = 49 -2y
5y +24 = 49
5y = 25
y = 5
Answer:
y=5
Step-by-step explanation:
7(y+2)-(4y-10) = 44-2y+5 distribute on the left and combine like terms on the right side of the equation
7y + 14 -4y +10 = 49 - 2y move every term with a variable on the left side with a change sign and the numbers on the right side
7y-4y+2y =49 -14 -10
5y = 25 divide both sides by 5
y5/5=25/5 so
y=5

Which term best describes the graph of y = –2?
increasing
decreasing
constant
positive
Answers
Answer:
It would be constant.
Step-by-step explanation:
Since there is no x value, the line will have no slope and just be horizontal about y= -2.
If we draw the graph we will see that the function is a straight line parallel to the x-axis.
The graph y = -2 is best described as a constant function.
Option C is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
A function:
y = -2
To graph the function we will find the coordinates of the function y = -2.
For x = 0,
y = -2
For x = 1,
y = -2
For x = 2,
y = -2
For x = 3,
y = -2
We will see that for all x values the y value is -2.
If we draw the graph we will see that the function is a straight line parallel to x-axis.
Thus,
The graph y = -2 is best described as a constant function.

Answers
Answer:
The range of allowable weights is between 31.95 oz and 32.05 oz both included
Step-by-step explanation:
w= allowable weights
I w-32 I ≤ 0.05
-0.05 ≤ w-32 ≤0.05
31.95 ≤ w ≤ 32.5
The range of allowable weights is lies between 31.95 ≤ w ≤ 32.5
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
We are given that food manufacturer makes 32-oz boxes of pasta. not every box weighs exactly 32 oz.
The allowable difference from the ideal weight is at most = 0.05 oz.
Let w= allowable weights
Then we have;
I w-32 I ≤ 0.05

The following shows the process a student used to determine the number of yards in 3,218 meters.
(1 mile = 1,609 meters)
(1 mile = 1,760 yards)
Step 1: 1,609 meters is being multiplied by conversion factor 1 mile over 3,218 meters equals 0.5 mile
Step 2: 0.5 mile is being multiplied by conversion factor 1760 yards over 1 mile equals 880 yards
Step 3: 880 yards
What was the error made in this conversion?
The 1 mile and 3,218 meters in Step 1 should be switched.
The 1,609 meters and the 3,218 meters in Step 1 should be switched.
The conversion factor should be added in Step 2 instead of being multiplied.
The conversion factor should be divided in Step 2 instead of being multiplied.

that is 316, 800 feet per hour for the swordfish
and 300,000 meters per hour for the passenger train

multiply 60 by 5,280 because there are 5,280 feet in a mile
multiply 300 by 1000 because there are 1000 meters in a kilometer *hence the prefix kilo
60 mph * 5,280 feet = 316800 fph
