The transformation represents a horizontal of 2 units to the right and a vertical of 5 units up
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the initial coordinates of the point be represented as P
Now , the coordinates of P = P ( x , y )
And , the transformed point be represented as Q
Now , the coordinates of Q = Q ( x - 2 , y + 5 )
when x → ( x - 2 )
The graph is moved 2 units to the right
And , when y → ( y + 5 )
The graph is moved 5 units up
Substituting the values in the equation , we get
The transformation is 2 units to the right and 5 units up
Hence , the transformation is 2 units to the right and 5 units up

Find the distance of a chord of Length 16cm From the centre of a Circle of radius 12.Cm.
The distance of the chord from the center of the circle is derived to be equal to √80 cm or 8.9 cm to the nearest tenth using the Pythagoras rule.
What is the Pythagoras rule?The Pythagoras rule states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The the distance can be observed to be of the side of a right triangle with the hypotenuse as the radius of the circle and the base side half of the chord, if x is used to represent the distance of the chord from the centre of the circle.
so by Pythagoras rule we can write:
12² = x² + 8²
144 = x² + 64
x² = 144 - 64 {collect like terms}
x² = 80
x = √80 {take square root of both sides}
x = 8.9443
Therefore, the distance of the chord from the center of the circle is derived to be equal to √80 cm or 8.9 cm to the nearest tenth using the Pythagoras rule.

How to model the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
The slope m represents the rate of change.The intercept b represents the value of y when x = 0.The intercepts are given by the values of each home in 1950, thus:
Idaho: 35500.Delaware: 55000.The slopes are given by the average change over the 50 years, hence:
Idaho: m = (106300 - 35500)/50 = 1416.Delaware: m = (130400 - 55000)/50 = 1508.As the number of years must be positive, Delaware starts with the higher income and has a higher yearly increase, the two states will never have the same median house value.

Uriel collects aluminum cans, crushes them with a hand can-crushing machine, and turns the crushed cans in once a month for extra money. Uriel can crush 3 cans in 23 of a minute. What is the rate, in cans per minute, at which Uriel crushes aluminum cans?
If Uriel can crush 3 cans in 23 of a minute, Uriel crushes aluminum cans at a rate of 4.5 cans per minute.
The problem gives us information about the number of cans Uriel can crush and the time it takes him to do so. We want to find the rate at which he crushes the cans, which is a measure of how many cans he can crush per minute.
To find this rate, we use a proportion. A proportion is a statement that two ratios are equal. In this case, we can set up a proportion that relates the number of cans Uriel crushes to the time it takes him to do so, and the rate at which he crushes the cans:
3 cans / (2/3 min) = x cans / 1 min
Here, the first ratio is the number of cans Uriel can crush in 2/3 of a minute (which is the same as saying that he can crush 3 cans in 2/3 of a minute). The second ratio is the unknown rate at which Uriel crushes cans per minute.
To solve for the unknown rate, we use cross-multiplication. This involves multiplying both sides of the proportion by the same value in order to isolate the unknown variable on one side of the equation.
In this case, we can cross-multiply by the denominators of each ratio:
3 cans × 1 min = (2/3 min) × x cans
Simplifying the left-hand side, we get:
3 cans × 1 min = 3 cans/min
Simplifying the right-hand side, we get:
(2/3 min) × x cans = 2x/3 cans/min
Putting these together, we get the equation:
3 cans/min = (2x/3) cans/min
We can now solve for x by isolating it on one side of the equation. To do this, we can multiply both sides by 3/2:
(3/2) × 3 cans/min = x cans/min
Simplifying, we get:
4.5 cans/min = x cans/min
Therefore, Uriel crushes aluminum cans at a rate of 4.5 cans per minute.

in a particular region during a 1-year period, there were 1000 deaths. it was observed that 321 people died of a renal failure and 460 people had at least one parent with renal failure. of these 460 people, 115 died of renal failure. calculate the probabil ity of a person that he dies of renal failure if neither of his parents had a renal failure
The probability of a person dying of renal failure if neither of their parents had renal failure is 0.056 or about 5.6%.
To solve this problem, we can use Bayes' theorem, which states that:
P(A|B) = P(B|A) * P(A) / P(B)
where P(A|B) is the probability of event A given that event B has occurred, P(B|A) is the probability of event B given that event A has occurred, P(A) is the prior probability of event A, and P(B) is the prior probability of event B.
In this case, we want to find the probability of a person dying of renal failure given that neither of their parents had renal failure. Let's define the following events:
R: death due to renal failure
P: at least one parent with renal failure
NP: neither parent has renal failure
We are given the following information:
Total deaths = 1000
Deaths due to renal failure (R) = 321
People with at least one parent with renal failure (P) = 460
Deaths due to renal failure among people with at least one parent with renal failure = 115
Using this information, we can calculate the probabilities as follows:
P(R) = 321/1000
P(P) = 460/1000
P(R|P) = 115/460
To find the probability of a person dying of renal failure given that neither of their parents had renal failure (i.e., P(R|NP)), we need to use Bayes' theorem. We can start by finding the probability of neither parent having renal failure (i.e., P(NP)):
P(NP) = 1 - P(P) = 1 - 0.46 = 0.54
Next, we can use the law of total probability to find the probability of dying of renal failure among people with neither parent having renal failure:
P(R|NP) = P(R) * P(NP|R) / P(NP)
We can find P(NP|R) using the formula:
P(NP|R) = P(NP ∩ R) / P(R)
To find P(NP ∩ R), we can use the formula:
P(NP ∩ R) = P(R|NP) * P(NP)
Substituting the values, we get:
P(R|NP) = P(R) * P(NP|R) / P(NP)
= 321/1000 * (1 - 115/460) / 0.54
= 0.056
This calculation shows how conditional probabilities can be calculated using Bayes' theorem and the law of total probability.

Answer: 25 sessions
Step-by-step explanation:
Set up an equation.
50+10x=12x
50=2x
x=25
She will have to take 25 sessions for both gym costs to be the same.
You can check this too. 50 plus 10*25 is $300, and 12*25 is $300.
(っ◔◡◔)っ ♥
Hope this helps.
MM4343
Answer: We can start by setting the cost of the two gyms equal to each other and then solving for the number of sessions. Let's call the number of sessions Macy takes x. The cost of Avery's gym is 50 + 10x, and the cost of Gabe's gym is 12x. Setting these two equal to each other, we have:
50 + 10x = 12x
Subtracting 12x from both sides:
50 = -2x + 10x
Simplifying:
50 = 8x
Dividing both sides by 8:
x = 6.25
So, Macy would need to take 6.25 sessions for the cost of both gyms to be the same. However, since she can only take whole number of sessions, she would need to take 7 sessions to make both gyms cost the same.

D - Decrease a number by 30 is the same as multiplying by 70.
Answer:
A - Decrease a number by 30% is the same as multiplying by 70%.
Step-by-step explanation:
This statement is incorrect. Decreasing a number by 30% means that the number will be reduced by 30% of its original value. For example, if the original number is 100, decreasing it by 30% would give you 100 - 30% * 100 = 100 - 30 = 70. On the other hand, multiplying a number by 70% would increase it by 70% of its original value, which is a different operation.
C - Decrease a number by 0.30 is the same as multiplying by 0.70.
This statement is also incorrect. Decreasing a number by 0.30 means subtracting 0.30 from the original number, while multiplying by 0.70 means multiplying the original number by 0.70. These are two different operations that will result in different results.

(f − g)(x) = x + 13
(f − g)(x) = x − 13
(f − g)(x) = 13x + 13
(f − g)(x) = 13x −13
Answer:
Step-by-step explanation:
(f - g) (x) = f(x) - g(x)
Given that f(x) = 7x + 5 and g(x) = 6x - 8, we can substitute these values into (f - g) (x):
(f - g) (x) = (7x + 5) - (6x - 8)
(f - g) (x) = 7x + 5 - 6x + 8
(f - g) (x) = x + 13
So, the answer is (f - g) (x) = x + 13
To find how many more texts were sent this week than last week we use,
(f − g)(x) = x + 13.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

The percent probability that Isabella will roll a 14 is 0%, since the dice she is using has a sample space of 1 through 12 and there is no 14 on the dice. Therefore, the probability of her rolling a 14 is 0%.
The probability of Isabella rolling a 14 with a 12-sided dice is 0%. This is because the sample space of the dice is 1 through 12, and there is no 14 on the dice. In order to calculate the probability, you would need to take the number of possible outcomes (the sample space) and divide it by the number of outcomes you are looking for. In this case, the sample space is 12 and the outcome being searched for is 1, giving you 12 divided by 1 which is 0. This means that the probability of Isabella rolling a 14 is 0%. This is because the sample space does not contain a 14, thus making it impossible for Isabella to roll a 14.
