Look at the graph shown below:
A coordinate plane is shown. A line passes through the y-axis at −1 and through the point 1 comma 2.
Which equation best represents the line?
y = 1 over 3.x − 1
y = 3x − 1
y = −x + 1 over 3.
y = 3x + 1
Answer:
(0,4),(-4,1)
y=mx+b, m=(y2-y1)/(x2-x1)
m=(4-1)/(0-(-4))
m=3/4
b=4
y=3/4x+4
Max's Market sells 6 eggs for £2.16.
Groceries Galore sells 8 eggs for £2.72.
Fancy Foodstuffs sells 12 eggs for £3.96.
Which shop's price per egg is better?
A. Max's Market B. Groceries Galore C. Fancy Foodstuffs
Answer:
C - Fancy Foodstuffs
Step-by-step explanation:
A = 6 eggs for £2.16
1 egg = £2.16 / 6 = £0.36
B = 8 eggs for £2.72
1 egg = £2.72 / 8 = £0.34
C = 12 eggs for £3.96
1 egg = £3.96 / 12 = £0.33

Determine its population on January 1st of a certain year. Write an
exponential function to represent the city’s population, y, based on the
number of years that pass, x after a period of exponential growth. Describe
the variables and numbers that you used in your equation.
2. Find another city whose population starts larger than the city in part (a), but
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
the variables and numbers that you used in your equation.
3. Explain the similarities and differences between your equations in (a) and
(b).

the population of city (b)? Show all of your work and explain your steps.
PLEASE USE PARIS AND CHICAGO FOR THE CITIES
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.

Answer:
60 degrees
Step-by-step explanation:
This would be the correct answer because angles 1 and 3 are vertical angles so before you move line y, 5 degrees, angle 3 would be 55 degrees too. Since you are moving line y, clockwise, angles 1 and 3 would get bigger by 5 degrees so you would add 5 degrees to 55. 55 + 5 = 60.
So your answer would be 60 degrees.

Answer:
11
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
1/2 ( 4^2 + √25 + 1)
= 1/2 (16 + √25 + 1)
= 1/2 ( 16 + 5 + 1)
= 1/2 ( 21 + 1)
= 1/2 (22)
= 1/2 x 22/1
= 22/2
= 11/1 = 11

N (7,0)
T (3, 3) U (5, 6)
Answer:
Step-by-step explanation:
Answer:
m, you go over five up 4, n, you go over 7 and stay there, t, you go over 3 and then go up 3, u, you go over 5 up 6, after you have all of those you conect them, m-n-t-u.
Two lines, C and D, are represented by the equations given below:
Line C: y = x + 14
Line D: y = 3x + 2
Which of the following shows the solution to the system of equations and explains why? (5 points)
Group of answer choices
(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
(6, 20), because both lines pass 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.
