The given functions f(x) = 3x + 6 and g(x) = (x+5)/3 are not inverses of each other, as their compositions of functions are not equal.

When we want to check if two functions are inverses of each other, we need to verify if composing the functions in both orders results in the input variable. In other words, we need to check if (f ∘ g)(x) = x and (g ∘ f)(x) = x, where f and g are the two functions.

For this problem, we have two functions:

f(x) = 3x + 6

g(x) = (x + 5)/3

Let's start by computing (f ∘ g)(x):

(f ∘ g)(x) = f(g(x)) = f((x + 5)/3) = 3((x + 5)/3) + 6

We can simplify this by canceling the 3's:

(f ∘ g)(x) = x + 5 + 6 = x + 11

Now let's compute (g ∘ f)(x):

(g ∘ f)(x) = g(f(x)) = g(3x + 6) = ((3x + 6) + 5)/3

Again, we can simplify this by canceling the 3's:

(g ∘ f)(x) = (3x + 11)/3

We can see that neither (f ∘ g)(x) nor (g ∘ f)(x) is equal to x, so we can conclude that the functions f(x) = 3x + 6 and g(x) = (x + 5)/3 are not inverses of each other.

Answer:

Nick is 6

Andrea is 18

Step-by-step explanation:

Sounds like a system of equations

Letting...

a = Andrea

n = Nick

Since she's 3 times the age, the first equation will be

a = 3n

Since in 10 years, Andrea will be 12 years older than Nick, we can write

a = n + 12

Since we have two a = ,we can set them equal to each other

3n = n + 12

Subtracting n

3n - n = 12

Now combining the n's (n is the same as 1n)

2n = 12

And last but not least, we can divide by 2

n = 6... so Nick is 6 right now.

Going back to our first equation of a = 3n, if we plug 6 in

a = 6(3) = 18.

y = -10×0 + 300

y = 300

Putting x = 5 in the equation:

y = -10×5 + 300

y = -50 + 300

y = 250

Putting x = 8 in the equation:

y = -10×8 + 300

y = -80 + 300

y = 220

Putting x = 10 in the equation:

y = -10×10 + 300

y = -100 + 300

y = 200

Putting x = 30 in the equation:

y = -10×30 + 300

y = -300 + 300

y = 0

The required ordered pair represents the center of the new circle after the transformation is (-x,y). Option A is correct.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them.

Here,
If a circle is reflected across the y-axis, its center, which was originally located at (x, y), will move to a new location that is the same distance from the y-axis but on the opposite side. Since the y-coordinate does not change during a reflection across the y-axis, the y-coordinate of the new center will remain the same as the original, which is y.

However, the x-coordinate will be negated, since the reflection across the y-axis involves flipping points to the opposite side of the y-axis. Therefore, the center of the new circle will have the coordinates (-x, y).

The probability that the next component brought in for repair is a compact disc player given that it is already known to be an audio component is 0.83 or 83%.

Probability is a fundamental concept in mathematics, statistics, and various fields of science. It is used to measure the likelihood of an event occurring

In the given scenario, we are told that a certain shop repairs both audio and video components. Let A denote the event that the next component brought in for repair is an audio component, and let B be the event that the next component is a compact disc player. We are also given that P(A) = 0.6 and P(B) = 0.5.

The probability of B given A, denoted by P(B|A), represents the probability that event B will occur given that event A has already occurred. In other words, it tells us how likely it is that the next component brought in for repair is a compact disc player given that it is already known to be an audio component.

To calculate P(B|A), we use the formula for conditional probability:

P(B|A) = P(A and B) / P(A)

Here, P(A and B) denotes the probability that both events A and B occur. We know that event B is contained in event A, so it follows that P(A and B) = P(B). Therefore:

P(B|A) = P(B) / P(A)

Substituting the given values, we have:

P(B|A) = 0.5 / 0.6

P(B|A) = 5/6 or 0.83 (rounded to two decimal places)

The lower bound for the number of minutes it takes for all the people to leave is 67 minutes.

What is lower bound?

Lower bound refers to the smallest possible value in a range or interval of values. In the context of measurements or estimates, it represents the minimum value that a quantity or measurement is expected to be, based on the precision or accuracy of the measuring instrument or method.

To calculate the lower bound for the number of minutes it takes for all the people to leave, we need to use the following formula:

Lower bound = (total number of people - 0.5) / departure rate (in people per minute)

Using the given information, we have:

Total number of people = 29800 (correct to the nearest 100)

Departure rate = 400 (correct to the nearest 50)

To ensure we have a conservative estimate, we will round down the total number of people to 29750 and round up the departure rate to 450.

Therefore, the lower bound for the number of minutes it takes for all the people to leave is:

Lower bound = (29750 - 0.5) / 450

= 66.1 (rounded up to the nearest minute)

So the lower bound for the number of minutes it takes for all the people to leave is 67 minutes.

The required, Rich's monthly mortgage payment will be $1,246.91.

A mortgage payment is the amount of money that a borrower pays to a lender in order to repay a home loan.

Here,
The amount that Rich is financing with the mortgage is the difference between the total cost of the home and the down payment:

Amount financed = $244,800 - 0.15($244,800) = $208,080

To calculate the monthly mortgage payment, we can use the formula for the present value of an annuity,
[tex]PMT = (PV * r) / (1 - (1 + r)^{-n}[/tex]

First, we need to calculate the monthly interest rate. Since the annual interest rate is 5.25%, the monthly interest rate is:

r = 0.0525 / 12 = 0.004375

Next, we need to calculate the total number of payments. Since Rich is taking out a 25-year loan, he will be making 25 x 12 = 300 monthly payments.

Now we can plug these values into the formula and solve for PMT:

PMT = ($208,080 × 0.004375) / (1 - (1 + 0.004375)^(-300))

= $1,246.91

Therefore, Rich's monthly mortgage payment will be $1,246.91.

Let's use algebra to solve the problem.

Let x be the number of phone calls Tammy received on the first evening.

According to the problem, she received 6 fewer calls on the second evening than on the first evening. This means that the number of phone calls she received on the second evening is x - 6.

The problem also states that she received 4 times as many calls on the third evening as she did on the first evening. This means that the number of phone calls she received on the third evening is 4x.

We know that Tammy received a total of 108 phone calls over the three evenings. We can use this information to set up an equation:

x + (x - 6) + 4x = 108

Simplifying the equation:

6x - 6 = 108

Adding 6 to both sides:

6x = 114

Dividing both sides by 6:

Answer:

change the 2w value

Step-by-step explanation:

first, check the equation:

14w + 21 = 14w + 20

when subtracting the 14w from both sides you can see that

21 is NOT EQUAL to 20, making the answer NS.

now, reread the question... create a new equation with ONE solution.

to fix this, we need to change the amount of W's, NOT the amount of constant.

let's try out another number in place of 2w

7 ( 3w + 3 ) = 14w + 20

21 w + 21 = 14w + 20

7 w = -1

w = -1/7

so now it is clear. to change the outcome of the equation, try out another value instead of 2w. Maybe try 3w, 3.5w, or maybe even 1w, or 1.5w .

Answer:

change the 2w

Step-by-step explanation:

=> 7 ( 3w + 3 ) = 14w + 20

=> 21 w + 21 = 14w + 20

=> 7 w = -1

=> w = -1/7

So everything is now evident. Change the value of 2w to anything else to alter the equation's result. Try 3w, 3.5w, or even 1w or 1.5w if you can.
