The graphs of linear functions f and g are shown on the grid.
Which function is best represented by the graph of g?
A g(x) = f(x) − 4
B g(x) = 1/3 f(x)
C g(x) = f(x) − 2
D g(x) = 3f(x)
Answer:
b
Step-by-step explanation:
The function [tex]g(x)=\dfrac{1}{3}f(x)[/tex] is best represented by the graph of g. Option B is correct.
Given information:
From the given graph of functions f and g, it can be observed that the inclination of f is more than that of function g.
Inclination signifies the angle it makes with the x-axis and slope is the tan of inclination. Greater the value of the slope, greater will be the inclination.
From the graph, the slope of function f is more than the slope of function g. Functions f and g pass through the origin and they both are straight lines.
So, dividing the function f(x) by a constant will reduce the slope of the function g(x). So, the correct function should be [tex]g(x)=\dfrac{1}{3}f(x)[/tex].
Function g(x) = f(x) − 4 represents that the slope of f and g is same. So, it is incorrect.
Function g(x) = f(x) − 2 represents that the slope of f and g is same. So, it is incorrect.
Function g(x) = 3f(x) represents that the slope of g is three times that of f. So, it is incorrect.
Therefore, the function [tex]g(x)=\dfrac{1}{3}f(x)[/tex] is best represented by the graph of g. Option B is correct.

The population of Chicago, Illinois, in 2003 was 2,869,121. The area of Chicago was 227.1 square miles. What was the average number of people living in 1 square mile?
Answer:
12,633.7
Step-by-step explanation:
population of Chicago, in 2003 = 2,869,121
The area of Chicago = 227.1 square miles.
What was the average number of people living in 1 square mile?
Average number of people living in 1 square mile also refers to the population density of Chicago
Average number of people living in 1 square mile = Total population / total square miles

Brooke needs a new computer. On Friday, the computer was $200.00. On Saturday, the price of the computer was $149.00. Determine if there was a markup or markdown and by what percent.
Answer:
Step-by-step explanation:
Given
price of the computer on Friday = $200
price of the computer on Saturday = $149
Difference in price = 200 - 149 = $51
Since the price reduces in price by $51, hence there was a markup in price.
% markup = difference in price/original price * 100%
% mark up = 51/200*100%
% markup = 51/2
% markup = 25.5%
Hence the markup was a 25.5% change

How to find value of complex number from graph?
To find the value of a complex number from the graph, follow the steps below.
On the graph where x-axis represents the real line, the distance of the point give the real number.On the graph where y-axis represents the imaginary line, the distance of the point give the imaginary number, which is written with complex number i.The image shows w and z + w. The point w is 1 units left from the imaginary axis. Thus, the real number for w is -1.
This number is 2 units down. Thus, the complex number represent the point w is,
[tex]w=-1-2i[/tex] ......1
Similarly, z+w is 4 units left and 4 units up. Thus, the complex number represent z+w is,
[tex]z+w=-4+4i[/tex] ......2
Substrate equation 1 from equation 2,
[tex]z+w-w=-4+4i-(-1-2i)\\z=-4+4i+1+2i\\z=-3+6i[/tex]
Hence, In the image which shows the complex number w and z+w, the value of the complex number Z is -3+6i.

Given : The smaller moon of Mars, Deimos, has a diameter of 7.5 miles.
The larger moon, Phobos, has a diameter that is [tex]1\dfrac34[/tex] times greater.
Diameter of Phobos = [tex]1\dfrac34\times\text{(Diameter of Deimos )}[/tex]

Find the 13th term in the following arithmetic sequence
2, 10, 18, 26, ...
Answer:
Find the 13th term in the following arithmetic sequence
2, 10, 18, 26 ...192 is the 13th term
Answer:
a(13) = 98
Step-by-step explanation:
a(n) = a1 + (n-1) d
a1 would be the original term, 2
since you are looking for the 13th term a(n) and n is 13
a(13) = 2 + (13-1) d
d would be the difference between each term, 8
a(13) = 2 + (13-1) 8
Now solve
a(13) = 2 + 12 * 8
a(13) = 2 + 96
a(13) = 98
The total cost in dollars for Larry to have his birthday party at a local
Trampoline Park can be found using the function t = 6.95p + 29.95, where p is
the number of people who will attend the party. If Larry only has $70 to spend on
his party, which of the following could represent the domain of the function?
Answer:
He can have 5 people at max
Step-by-step explanation:
He can only have 5 people at max which would cost $64.70, since if there were one more it'd cost $71.65. So the equation would be
T = 6.95p + 29.95 { 0 ≤ x ≤ 5 }
The domain can be represented as 0 ≤ p < 6
What is domain of the function ?Domain is the set of all inputs for which the function is valid, whereas the range of a function is the set of outputs that the function will produce. Also, we can define domain and range as, domain is the set of numbers which are valid values for the independent variable. The range is the set of valid numbers for the dependent variable.
We have
t = 6.95p + 29.95
Amount = $70
Required
Determine the domain
First, we need to solve for p
Substitute $70 for t in t = 6.95p + 29.95
70 = 6.95p + 29.95
Collect Like Terms
6.95p = 70 - 29.95
6.95p = 40.05
Solve for p
p = 40.05/6.95
p = 5.76
This implies that Larry can not invite up to 6 people.
Hence, the domain can be represented as 0 ≤ p < 6
