Answer:
Step-by-step explanation:
To find the inverse of the function f(x) = 4x - 2, we need to switch the roles of x and y, and then solve for y:
x = 4y - 2
x + 2 = 4y
y = (x + 2) / 4
So the inverse of f(x) is g(x) = (x + 2) / 4.
To graph f(x) and g(x), we can plot their points on the same coordinate system. Here is the graph:
Graph of f(x) and g(x)
The blue line represents f(x) = 4x - 2, and the orange line represents g(x) = (x + 2) / 4, which is the inverse of f(x). Notice how the two lines are reflections of each other across the line y = x, which is a characteristic of inverse functions.
The inverse of the function is f-1(x) = (x + 2)/4
How to determine the inverse of the functionInverse functions are pairs of functions that "undo" each other.
Specifically, if a function f maps x to y, its inverse function g maps y back to x such that g(f(x)) = x and f(g(y)) = y for all values of x and y in their respective domains
From the question, we have the following parameters that can be used in our computation:
f(x) = 4x - 2
Rewrite as
y = 4x - 2
Swap x and y
So, we have
x = 4y - 2
This gives
4y = x + 2
Divide by 4
y = (x + 2)/4
This means that the inverse is f-1(x) = (x + 2)/4

1/2 - 1/4
Answer:
1/4
Step-by-step explanation:
You cannot subtract (or add) a fraction with different denominators so first, you need to find a common denominator. You can do this by finding the least common multiple (LCM).
Here the denominators are 2 and 4 so the LCM is 4.
After you find the LCM you need to multiply the denominator by a number that equals the LCM. Then multiply the numerator by that same number.
So convert both 1/2 and 1/4
1/4 x 1/1 = 1/4
1/2 x 2/2 = 2/4
Now we can just subtract the numerator from each other.
2/4 - 1/4 = 1/4
We cannot simplify the difference any more so keep it the same.
What is 0700 military time?
0700 military time is 7:00 AM in the 24-hour time format used by the military, also known as the 24-hour clock.
The 24-hour clock is a timekeeping system that uses a continuous count of 24 hours, instead of two sets of 12 hours for AM and PM. In this system, each hour of the day is numbered from 0 to 23, and is referred to as "military time" or "24-hour time". So, 0700 military time is equivalent to 7:00 AM, with the "0" indicating the first hour of the day. This system is commonly used in the military, as well as in other fields where precise and standardized timekeeping is important, such as aviation and public transportation.

1 mile = 5,280 feet
45 miles per hour
46 miles per hour
47 miles per hour
48 miles per hour
48 miles per hour is the most accurate rate of speed Morris is traveling
What is Unit of measurement?A measurement unit is a standard quantity used to express a physical quantity.
Given that Aneesha's speed is 50 miles per hour.
We need to convert to feet per second.
By given 1 mile = 5,280 feet
50×5280=264000 feet
Now divide by 36000
264000/36000
73.33 feet/second is the Aneeshas speed.
Morris is traveling 3 feet per second less than Aneesha, so his speed is:

why does the equation y = 3x + 5 not represent a proportional relationship?
Answer:
Proportional relationship between two quantities x and y means that the quotient y/x stays constant, i.e. that there is a constant c such that y=cx. In our case we have that y=3x+5 which means that x and y are NOT proportional.
Answer:
Check the explanation provided
Step-by-step explanation:
This equation does not represent a proportional relationship because it's graph does not pass through the origin (i.e. 0,0)
[tex]y = mx + c[/tex]
where m = gradient OR slope
= 3
c = y-intercept
= 5

Determine the future value of a simple interest investment where 5% interest paid monthly for
1.5 years on $1000.
Answer:
Step-by-step explanation:
The simple interest formula is given by I = Prt, where P is the principal amount, r is the interest rate (per compounding period), and t is the time in years.
In this case, the interest rate is 5% per month, so we need to convert it to the equivalent annual interest rate, given by r = (0.05 x 12) = 0.6 (since there are 12 months in a year).
The time is 1.5 years, so t = 1.5.
So, the simple interest is:
I = Prt = 1000 x 0.6 x 1.5 = 900
The future value of the investment is the principal amount plus the interest earned, given by:
Future value = P + I = 1000 + 900 = 1900
So, the future value of the investment is $1900.
Answer: the future value of the simple interest investment, where 5% interest is paid monthly for 1.5 years on $1000, is $18074.06.
Step-by-step explanation:
To determine the future value of a simple interest investment, we need to calculate the interest earned over the investment period and add it to the original investment amount. Here's a step-by-step explanation for calculating the future value of a simple interest investment with a 5% interest rate paid monthly for 1.5 years on $1000:
Step 1: Convert the annual interest rate to a monthly rate.
Since the interest rate is 5% per year and the interest payments are made monthly, we need to convert the annual interest rate to a monthly interest rate. We can do this by dividing the annual interest rate by 12:
Monthly interest rate = Annual interest rate / 12
Monthly interest rate = 5% / 12 = 0.05 / 12 = 0.00417
Step 2: Calculate the interest payment for each month.
For each month, we can calculate the interest payment by multiplying the monthly interest rate by the current balance:
Interest payment = Monthly interest rate * Current balance
Let's calculate the interest payment for the first month:
Interest payment = 0.00417 * $1000 = $4.17
Step 3: Add the interest payment to the current balance to get the new balance.
After each interest payment, we can add it to the current balance to get the new balance:
New balance = Current balance + Interest payment
New balance = $1000 + $4.17 = $1004.17
Step 4: Repeat the steps for each month.
We can repeat steps 2 and 3 for each of the 12 months in the first year and then for the 6 months in the second year.
Step 5: Add up the final balance.
After all 18 interest payments have been made, the final balance will be the sum of all the new balances:
Final balance = $1004.17 + $1004.17 + ... + $1004.17 (18 times) = $1004.17 * 18 = $18074.06
So, the future value of the simple interest investment, where 5% interest is paid monthly for 1.5 years on $1000, is $18074.06.

How to convert microgram to mg?
To convert micrograms (μg) to milligrams (mg), you can divide the number of micrograms by 1000. So, the formula for converting micrograms to milligrams is: mg = μg / 1000.
To convert micrograms to milligrams, divide the number of micrograms by 1000. This is because there are 1000 micrograms in 1 milligram. For example, if you have a measurement of 5000 micrograms and you want to convert it to milligrams, you would divide 5000 by 1000 to get 5 milligrams. This conversion is useful in many fields, including medicine, where medication dosages are often measured in milligrams, and scientific research, where precise measurements of small amounts of substances are necessary.
For example, let's say you have a measurement of 5000 micrograms and you want to convert it to milligrams:
mg = 5000 μg / 1000
mg = 5 mg
Therefore, 5000 micrograms is equal to 5 milligrams.

Sanjeev has to buy enough wallpaper to cover a rectangular wall that has an area of
242 square feet. The wall is 11 feet tall. How wide is the wall?
The foundation of a building is in the shape of a rectangle, with a length of 20 meters (m) and a width of 18 m.
The distance from the top left corner of the foundation to the bottom right corner is 27 meters.
The distance between two points in space can be calculated using the Pythagorean theorem. In this case, we want to find the distance from the top left corner of the foundation to the bottom right corner.
To do this, we will use the length and width of the foundation, which are 20 meters and 18 meters respectively.
The Pythagorean theorem states that in a right triangle, the square of the distance (c) between the two points is equal to the sum of the squares of the other two sides (a and b). Mathematically, this can be represented as
=> c² = a² + b².
In our case, the two sides are the length (20m) and width (18m) of the foundation. To find the distance, we will first find the square of c by adding the squares of a and b. So,
=> c² = 20² + 18² = 400 + 324 = 724.
To find the distance, we will take the square root of c².
So,
c = √724 = 26.83
When we rounded to the nearest meter, c = 27m.
