The y-intercept of (f − g)(x) is 8. Therefore, option C is the correct answer.
Given various values of the linear functions f (x) and g(x) in the table.
What is a y-intercept?An intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
For the function f(x)
Here, (-6, 20) and (-4, 14)
Slope =(14-20)/(-4+6)
= -3
Substitute, m=-3 and (x, y)=(-6, 20) in y=mx+c, we get
20=-3(-6)+c
c=2
Substitute, m=-3 and c=2 in y=mx+c, we get
f(x)=-3x+2 --------(I)
For the function g(x)
Here, (-6, -36) and (-4, -26)
Slope =(-26+36)/(-4+6)
= 10/2 =5
Substitute, m=5 and (x, y)=(-6, -36) in y=mx+c, we get
-36=5(-6)+c
c=-6
Substitute, m=5 and c=-6 in y=mx+c, we get
g(x)=5x-6 --------(II)
Now, (f − g)(x)=-3x+2-(5x-6)
= -3x+2-5x+6
= -8x+8
Here, y-intercept is 8
The y-intercept of (f − g)(x) is 8. Therefore, option C is the correct answer.

What are linear equations?
A linear equation is one with variables of power 1, such as ax+b = 0, where x is the variable and a and b are fundamental values. Equations are claims that two mathematical expressions comprising one or more variables are equal. The term "linear equation" refers to an equation where the greatest power of the variable is one.
Since the budget is y, the total amount spent on fuel must be less than or equal to the budget. Since it is $2.85 per gallon, the correct equation would be [tex]y\leq 2.85x[/tex].

kevin opened a savings account with texas national bank. his account has an apr of 1.75% compounded quarterly. if kevin opens his account with $2500, how long will it take for the account to earn $7500?
As per the concept of compound interest, it take 62.915 years for the account to earn $7500
Compound interest:
The general formula to calculate the compound interest is written as,
A = P(1 + r/n)^nt
where
A = Accrued amount (principal + interest)
P = Principal amount
r = Annual nominal interest rate as a decimal
n = number of compounding periods per unit of time
t = time in decimal years;
Given,
Compounding frequency = Quarterly
Interest rate = 1.75%
Opening balance = $2500
Final amount = $7500
Now, we have to calculate the time time for the person to achieve the final amount,
First, convert R as a percent to r as a decimal
r = R/100
r = 1.75/100
r = 0.0175 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(7,500.00/2,500.00) / ( 4 × [ln(1 + 0.0175/4)] )
t = ln(7,500.00/2,500.00) / ( 4 × [ln(1 + 0.004375)] )
t = 62.915 years
Therefore, the time required to get a total amount of $7,500.00 with compounded interest on a principal of $2,500.00 at an interest rate of 1.75% per year and compounded 4 times per year is 62.915 years.

What is a fraction?
A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, or three-quarters.
To rank the free throw accuracy of these players from lowest to highest, we need to compare the fraction of free throws made to the total number of free throws taken by each player.
The fraction of free throws made to the total number of free throws taken is called the free throw percentage.
The free throw percentage for each player can be calculated by dividing the number of free throws made by the number of free throws taken and expressing the result as a decimal.
For example, the free throw percentage for Smith can be calculated as follows:
Free throw percentage = 13/19 = 0.68
We can use this same method to calculate the free throw percentage for the other players:
Haller: Free throw percentage = 12/20 = 0.6
Dennis: Free throw percentage = 14/17 = 0.82
Ballard: Free throw percentage = 17/22 = 0.77
Based on these calculations, the free throw accuracy of these players can be ranked from lowest to highest as follows:
Haller: Free throw percentage = 0.6
Smith: Free throw percentage = 0.68
Ballard: Free throw percentage = 0.77
Dennis: Free throw percentage = 0.82
Hence, the free throw accuracy of these players can be ranked from lowest to highest as Haller, Smith, Ballard, and Dennis.

A cyclist rode 3.75 miles in 0.3 hours.
a. How fast was she going in miles per hour?
b. At that rate, how long will it take her to go 4.5 miles?
The speed of a cyclist rode 3.75 miles in 0.3 hours is 0.36 hours.
Given that, a cyclist rode 3.75 miles in 0.3 hours.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
A) We know that, speed =Distance/Time
Now, speed =3.75/0.3
= 12.5 miles per hour
B) Here, distance =4.5 miles and rate =12.5 miles per hour
Now, 12.5 =4.5/Time
⇒ Time =4.5/12.5
⇒ Time =0.36 hour

Step-by-step explanation:
A school sold 461 tickets for the school play. Student tickets cost $3 and adult tickets cost $4. Ticket sales totaled $1624.
Part A. Write and solve a system of equations to model this situation.
Part B. Then explain the meaning of your solution.
The system of equations to model this situation is given by;
x + y = 461
3x + 4y = 1624
The school sold 220 students tickets and 241 adult tickets.
How to write and solve equation?let
Number of students tickets = x
Number of adults tickets = y
x + y = 461
3x + 4y = 1624
From (1)
x = 461 - y
Substitute into (2)
3x + 4y = 1624
3(461 - y) + 4y = 1624
1383 - 3y + 4y = 1624
- 3y + 4y = 1624 - 1383
y = 241
Substitute into (1)
x + y = 461
x + 241 = 461
x = 461 - 241
x = 220
In conclusion 220 students tickets and 241 adults tickets were sold.

explain why a 2 x 2 matrix can have at most two distinct eigenvalues. explain why an n x 11 matrix can have at most n distinct eigenvalues.
An n x 11 matrix can have a maximum of n different eigenvalues, whereas a 2 x 2 matrix can only have a maximum of two. Below, there is a detailed explanation of this.
What is a matrix simple definition?a collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics.
What's the matrix theory?The study of matrices is the main focus of the mathematical field known as matrix theory. It started out as a branch of linear algebra but quickly expanded to cover topics in graph theory, algebra, combinatorics, and statistics.
solution of a 2 x 2 matrix is in given form:
|A - λI| = 0
here,
A = eigenvalue
I = identity matrix
now
|A - λI| = (a11 - λ)
(a22 - λ) - a12a21 = 0
the solutions of above equation are 2 x 2 matrix's eigenvalues.
just like this, a matrix of size n by n may have up to n different eigenvalues as its characteristic equation is a polynomial of nth degree with up to n roots (i.e. n eigenvalues). all due to the equation form: |A - I| = 0, where A is an eigen and I is an identity matrix.
by expanding the determinant:
|A - I| = (-1)
having coefficients c1, c2,..., cn, having sum = zero.
which is nth degree polynomial equation consisting of n possible solutions, that are basically n x n matrix's eigenvalues .

3x/2-5= 7
Please give full explanation
Answer:x=8
Step-by-step explanation:
3x/2-5=7
Move all terms not containing x to the right side of the equation by adding 5 to both sides
3x/2-5+5=7+5
3x/2=12
Multiply both sides of the equation by 2/3 to isolate x.
3x/2*2/3=12*2/3
x=24/3
x=8
Answer: x= 8
Step-by-step explanation:
3x/2-5=7
3x/2 = 12
3x = 24
x= 8
