The pair of lines 12x + 4y = 9 and 12x = 36y + 48 are perpendicular.
Determining whether the pair of lines are parallel, perpendicular or neitherFrom the question, we are to determine whether the pair of lines are parallel, perpendicular or neither
To determine whether the pair of lines are parallel, perpendicular, or neither, we need to compare their slopes.
We can rewrite both equations in slope-intercept form, y = mx + b,
Where m is the slope of the line:
12x + 4y = 9
4y = -12x + 9
y = (-3/1)x + 9/4
12x = 36y + 48
12x - 48 = 36y
(1/3)x - 4/3 = y
The slope of the first line is -3/1, and the slope of the second line is 1/3.
Parallel lines have the same slope, so these lines are not parallel.
Perpendicular lines have slopes that are negative reciprocals of each other, meaning their slopes multiply to -1. Therefore, these lines are perpendicular.
Hence, the given pair of lines are perpendicular.

(A.) f = 2x + 5
(B.) f(x) = 2x + 5
(C.) It is already written in function notation.
(D.) f(y) = 2x+ 5
The given expression is already written in function notation.
Solving linear equationFunction notation is a way of representing a mathematical relationship between two variables, where one variable (usually denoted as x) is the input and the other variable (usually denoted as y) is the output. In this case, y is a function of x, which means that the value of y depends on the value of x.
To write the linear equation y = 2x + 5 in function notation, we replace y with f(x) to get:
f(x) = 2x + 5
This means that f(x) is a function of x, where the output f(x) is equal to 2 times the input x plus 5. The variable f(x) represents the value of y for a given value of x.

The principal P is borrowed at a simple interest rate r for a period of time t. Find the simple interest owed for the use of the money. Assume 360 days in a year.
P = $370, r = 2%, t = 2 years
Step-by-step explanation:
Using the formula for simple interest:
Simple Interest = P * r * t
where P is the principal, r is the rate of interest, and t is the time in years.
Substituting the given values:
Simple Interest = $370 * 0.02 * 2 = $14.80
Therefore, the simple interest owed for the use of the money is $14.80.

If to help pay for culinary school, Keiko borrowed money from her credit union:
a. Keiko's monthly payment is $542.63.
b. The total amount to repay the loan is $65,115.60
c. The total amount of interest she will pay is $15,115.60
What is the monthly payment?(a) To find Keiko's monthly payment, we can use the formula for calculating the monthly payment for an amortized loan:
P = (r * A) / (1 - (1 + r)^(-n))
Where:
P =Monthly payment
A= loan amount
r = Monthly interest rate
n = Total number of payment
Plugging in the values for Keiko's loan, we get:
P = $50,000
r = 0.055 / 12 = 0.00458
n = 10 * 12 = 120
P = (0.055/12 * $50,000) / (1 - (1 + 0.055/12)^(-120)) = $542.63
(b) If Keiko pays the monthly payment each month for the full term, the total amount she will repay the loan will be:
Total amount = Monthly payment * Total number of payments
= $542.63* 120 = $65,115.60
(c) If Keiko pays the monthly payment each month for the full term, the total amount of interest she will pay will be:
Total interest = Total amount - Loan amount
=$65,115.60 - $50,000 = $15,115.60
So, Keiko will pay a total of $15,115.60 in interest over the 10-year term of the loan.

Describe Asymptotes?Asymptotes are points along a line that a curve approaches but never touches. The term "asymptote" refers to the point at which a function's graph converges. Asymptotes are often not necessary when graphing functions.
There are three distinct asymptotes.
Asymptote horizontal (HA) - Given that it is horizontal, its equation has the form y = k. The horizontal asymptote is the point at which the function f(x) tends to zero.
As it is a vertical line, the vertical asymptote's equation has the form x = k. When the denominator of a rational function approaches towards 0, vertical asymptotes are defined.
The equation for the slanting asymptote (also known as the oblique asymptote) is y = mx + b since the line is inclined.

Pls help I rly appreciate it! :)
The population in thousands of a town in the year 2007 is 16.56 thousand.
What use does the base value serve in an exponential function?In an exponential function, the base value controls how quickly the function increases or decreases. The function expands exponentially if the base value is more than 1, whereas it degrades exponentially if the base value is between 0 and 1. Faster growth or decay is indicated by a bigger base value.
Given that,
y = 8.5(1.1)ˣ
The value of x is calculated as:
x = 2007 - 2000 = 7 years.
Substitute the value of x in the given function:
y = 8.5(1.1)⁷
y = 16.56
Hence, the population in thousands of a town in the year 2007 is 16.56 thousand.

What is an Equations?Equations are mathematical statements that have two algebraic expressions on either side of equals (=) sign. The phrases written on the left and right sides are equal, as shown by this example.
Equations can be resolved in order to ascertain the value of a variable that represents an unknowable quantity. In the absence of the "equal to" symbol, a statement is not an equation. That will be taken into consideration as a phrase.
Lin’s teacher assigned each of them the same number of problems to complete.
Total number of problems assigned by Lin's teacher to students = 30
Let the total number of problems assigned to each student initially be x
So, the number of problems assigned to all the students initially = 5x
Also it is given that Lin's teacher assigns 2 more problems to each student
which means he gives 10 more problems to solve

A race official needs to know how long it takes an average contestant to run an obstacle course. There are a total of 200 contestants. How can he find a reasonable estimate for the amount of time it takes to run the obstacle course?
A. Time any contestant on the course and use that time
B. Time himself on the course and use that time
C. Time 2 contestants and average their times
D. Time 20 contestants and average their times
The best option to find a reasonable estimate for the amount of time it takes to run the obstacle course among 200 contestants is to option D: Time 20 contestants and average their times.
Define reasonable estimate?A reasonable estimate is an approximation that is based on logical reasoning and information available, and it is within a reasonable margin of error. It is not expected to be precise, but it is expected to provide a fair idea of the value being estimated.
For example, estimating the cost of a renovation project within 5% of the actual cost would be considered a reasonable estimate.
By timing only one contestant, the time might not be representative of the entire group since individual performances can vary significantly. Timing the race official himself also won't give an accurate estimate since the official might not be a typical contestant in terms of speed and agility.
On the other hand, timing 2 contestants and averaging their times might not provide a big enough sample size to get a good estimate.By timing 20 contestants, there is a higher chance that the sample size will be representative of the entire group, and the average time will provide a more accurate estimate of the typical performance on the obstacle course.

SquareRectangleCircleTriangleTrapezoidParallelogramIn the given question,
To find the area of a triangle, we need the length of two sides and the angle between them. We are given that the length of two sides of the triangle are 3 cm and 4 cm, and the angle between them is 30°.
We can use the formula for the area of a triangle, which is:
Area = (1/2) x base x height
We can take the side of length 3 cm as the base of the triangle, and the side of length 4 cm as the height, as it forms a right angle with the base. To find the height, we can use trigonometry.
sin(30°) = opposite/hypotenuse
sin(30°) = height/4
height = 4 x sin(30°)
height = 2 cm
Now, we can substitute the values in the formula for the area of the triangle:
Area = (1/2) x base x height
Area = (1/2) x 3 x 2
Area = 3 cm^2
Therefore, the area of the triangle is 3 cm^2.

a. The x-intercepts are 1/4 and 4. b. The vertex of the graph of f(x) is (1.875, 56), and it represents a maximum point on the graph.
What is axis of symmetry?The object's form is symmetrical because of the axis of symmetry, which is a straight line. On each of its sides, the axis of symmetry produces a perfect reflection. It could be lateral, vertical, or horizontal. The two sides of an object are the same if we fold and unfold it along the axis of symmetry. Various forms have various symmetry lines. There are four lines of symmetry in a square, two lines in a rectangle, infinite lines in a circle, and no lines of symmetry in a parallelogram. There are n axes of symmetry in a regular polygon with n sides.
We know that,
To find the x-intercepts, we set f(x) equal to 0 and solve for x:
-16x² + 60x + 16 = 0
4x² - 15x - 4 = 0
4x² - 16x + x - 4 = 0
4x (x - 4) - 1(x - 4) = 0
(4x - 1) (x - 4) = 0
x = 1/4
x = 4
The x-intercepts are 1/4 and 4.
The vertex of the graph of f(x) can be found using the formula x = -b/2a
x = -60 / (2(-16)) = 1.875
To establish whether the vertex is a maximum or minimum, we examine the shape of the coefficient of the x square term, which is negative (-16). This signifies that the graph expands down and the vertex is a maximum.
Hence, the vertex of the graph of f(x) is (1.875, 56), and it represents a maximum point on the graph.

Accordingly, if Britta only paid the interest during her two years of education, she would accrue about $33,782 in interest over the course of her loan.
what is interest ?The sum of money that a borrower must give a lender as interest is compensation for the use of borrowed funds. It is typically computed as a percentage of the principal, which is the amount borrowed, and is repaid alongside the principal over a predetermined amount of time. The cost of the lender, the likelihood of a default, and the desire for credit in the economy are just a few of the variables that affect the interest rate, or the percentage charged for borrowing the money.
given
We can use the following method to determine the total interest paid:
Principal x Interest Rate x Duration equals total interest.
where Principal denotes the sum borrowed, Interest Rate denotes the annual interest rate (in decimal form), and Time denotes the number of years over which interest will accrue.
Assume Britta took out a $50,000 loan to pay for her schooling.
Therefore, the amount of her loan at the conclusion of that time frame would be:
$50,000 x 1.06^2 = $56,420
The interest that will be charged on this balance for the remaining 10 years and 6 months of the loan period needs to be calculated now. Using the above method, we obtain:
$56,420 multiplied by 0.06 times 10.5 equals the total interest, or $33,782.

1.1
Step-by-step explanation:
-3+1.9 =-1.1
-3+1.1=-1.9
Answer:
-3 + 1.1 = -1.9
Step-by-step explanation:
Let us assume that,
→ Missing number = m
Now we have to,
→ Find the required value of m.
Forming the equation,
→ -3 + m = -1.9
Then the value of m will be,
→ -3 + m = -1.9
→ m - 3 = -1.9
→ m = -1.9 + 3
→ [ m = 1.1 ]
Hence, the value of m is 1.1.

[tex]\boxed{\tt 4x-(9-3x)=8x-1}[/tex]
Answer:
-8
Step-by-step explanation:
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1
7x = 8x + 8
x = -8
Therefore, the solution to the equation 4x - (9 - 3x) = 8x - 1 is x = -8.
Given:-
[tex] \sf \: 4x - ( 9 - 3x ) = 8x - 1[/tex][tex] \: [/tex]
Solution:-
[tex] \sf \: 4x - ( 9 - 3x ) = 8x - 1[/tex][tex] \: [/tex]
[tex] \sf \: 4x - 9 + 3x = 8x - 1[/tex][tex] \: [/tex]
[tex] \sf \: 4x + 3x - 9 = 8x - 1[/tex][tex] \: [/tex]
[tex] \sf \: 7x - 9 = 8x - 1[/tex][tex] \: [/tex]
[tex] \sf \: 7x - 8x = -1 + 9[/tex][tex] \: [/tex]
[tex] \sf \: -1x = 8[/tex][tex] \: [/tex]
[tex] \sf \: x = \cancel \frac{8}{ - 1} [/tex][tex] \: [/tex]

The side x of the similar triangle is 12.7 units.
How to find the side of a triangle?The triangles are similar triangle.
Two triangles are said to be similar when they have two corresponding angles congruent and the sides proportional.
Therefore, using the proportion
37- 5 / x = x / 5
Evaluate the difference of 37 and 5
32 / x = x / 5
Cross multiply the equation
x × x = 32 × 5
So, we have
x² = 160
Take the square root of both sides
x = √160
Evaluate the square roots
x = 12.6491106407
Hence, the value of x is x = 12.7 units (when approximated)

7. A pot of water is heated to 200°F. The table shows typical temperature readings for the pot. The room temperature is 70°F.
After 5 minutes the pot of water is 164°F. How long will it take the water to cool to 150°F? Round to the nearest minute.
A. About 4 min
B. About 3 min
C. About 8 min
D. About 6 min
The amount of time it would take the water to cool to 150°F is: C. About 8 min.
How to find an equation of the line of best fit for the data?In this scenario, the time would be plotted on the x-axis of the scatter plot while the temperature would be plotted on the y-axis of the scatter plot.
On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the line of best fit (trend line) on the scatter plot.
From the scatter plot (see attachment) which models the relationship between the time and temperature, an exponential equation for the line of best fit is given by:
[tex]y = 192e^{-0.028x}[/tex]
When temperature y = 150°F, the value of x (in minutes) can be calculated as follows:
[tex]150 = 192e^{-0.028x}[/tex]
ln(150/192) = -0.028x
x = -0.24686007793/0.028
x = 8 mins.
