so, [tex]\frac{15}{100} - \frac{726}{y}[/tex]
726x100=72600
72600 ÷ 15 = 4840

that during this same time experienced population decline. Determine its
population for January 1st of the same year you picked for part (a). Write an
exponential function to represent the city’s population, y, based on the
number of years that pass, x after a period of population decline. Describe

Answer:
The city we will use is Orlando, Florida, and we are going to examine its population growth from 2000 to 2010. According to the census the population of Orlando was 192,157 in 2000 and 238,300 in 2010. To examine this population growth period, we will use the standard population growth equation
where:
is the population after years
is the initial population
is the time in years
is the growth rate in decimal form
is the Euler's constant
We now for our investigation that , , and ; lets replace those values in our equation to find :
Now lets multiply by 100% to obtain our growth rate as a percentage:
=2.2%
We just show that Orlando's population has been growing at a rate of 2.2% from 2000 to 2010. Its population increased from 192,157 to 238,300 in ten years.
B. Here we will examine the population decline of Detroit, Michigan over a period of ten years: 2000 to 2010.
Population in 2000: 951,307
Population in 2010: 713,777
We know from our investigation that , , and . Just like before, lets replace those values into our equation to find :
= -2.9%.
We just show that Detroit's population has been declining at a rate of 2.2% from 2000 to 2010. Its population increased from 192,157 to 238,300 in ten years.
C. Final equation from point A: .
Final equation from point B:
Similarities: Both have an initial population and use the same Euler's constant.
Differences: In the equation from point A the exponent is positive, which means that the function is growing; whereas, in equation from point B the exponent is negative, which means that the functions is decaying.
D. To find the year in which the population of Orlando will exceed the population of Detroit, we are going equate both equations and and solve for t:
We can conclude that if Orlando's population keeps growing at the same rate and Detroit's keeps declining at the same rate, after 31.36 years in May of 2031 Orlando's population will surpass Detroit's population.
E. Since we know that the population of Detroit as 2000 is 951307, twice that population will be . Now we can rewrite our equation as: . The last thing we need to do is equate our Orlando's population growth equation with this new one and solve for t:
We can conclude that after 45 years in 2045 the population of Orlando will exceed twice the population of Detroit.

1. The answer is b ≥ 4
2. m = -11; m> -11
Step-by-step explanation:
1. solve your inequality step-by-step.
-4b + 9 ≤ -7
subtract nine from both sides.
-4b + 9-9 ≤ -7-9
-4b ≤ -16
then divide both sides by 4,
-4b/4 and -16/4,
you get: b ≥ 4
2. to solve:
2m+18>-4
subtract 18 from both sides.
2m + 18 -18 >-4 -18
= 2m>-22,
divide both sides by 2,
2m/2, -22/2
you end up with: m > -11

Ellen drew a graph showing the solution to an inequality.

Which inequality does Ellen’s graph show the solution to?
3.25 less-than 2.5 + r
3.25 greater-than 2.5 + r
Negative 3.25 less-than negative 2.5 + r
Negative 3.25 greater-than negative 2.5 + r
Answers
Answer:
Negative 3.25 greater-than negative 2.5 + r
Step-by-step explanation:
The solution Ellen drew is r < -0.75
This is the solution to -3.25 > -2.5 +r
-0.75 > r
add 2.5 to both sides
Hope it helped!
The inequality Ellen’s graph shows the solution to is, Negative 3.25 less-than negative 2.5 + r, the correct option is C.
What is an Inequality?An Inequality is a statement that is formed when two expressions are joined using an inequality operator.
A number line is a line segment that depicts the real numbers marked at a fixed distance, like a coordinate axis.
A graph is a representation of the relation between two variables, a graph is useful in determining the equation of the variables.
A number line going from negative 1.25 to positive 0.75. An open circle is at negative 0.75, everything to the left of the circle is shaded.
An open circle represents the number that is not included.
x < -0.75
x < -3.25 +2.5
x -2.5 < 3.25
It can also be written as,
Negative 3.25 less-than negative 2.5 + r.

(6, 20), because the point does not lie on any axis
(3, 11), because the point lies between the two axes
(3, 11), because one of the lines passes through this point

y=x+14 line 1
y=3x+2 line 2
These are both the equation of lines written in slope intercept form
y=mx+b where m is the slope and the point (0,b) is the y intercept.
The first line has a slope of m=1. The 2nd line has a slope of m=3
Since these lines have different slopes, they are not parallel, thus they will cross at some point. What you have to determine is where the lines cross, which will be a point (x,y) that is on both lines.
We already have y solved in terms of x from either equation so we can use substitution to solve the system.
Since y=x+14 from line 1, put x+14 in place of y in the equation of line 2.
x+14=3x+2
solve for x.
Subtract x from both sides...
14= 3x-x+2
14=2x+2
subtract 2 from both sides
14-2=2x
12=2x
divide both sides by 2
6=x
We now have the x value of the common point. Plug the value 6 in for x in one of the original equations and solve for y.
y=6+14
y=20
These two lines cross at the point (6,20) which is a point the two lines have in common.
