write the equation for the transformation of the graph of y=f(x). use the form f(x)=a(x-h)+k. 13. translated 2 units left and 7 units down. 14. translated 5 units right, 2 units up, and stretched by a factor of 3.
The equations of the graph after respective transformations are;
13) f(x) = a(x + 2) - 7
14) f(x) = 3(x - 5) + 2
13) In transformations, when we translate a function to the left, it means we will add the number of units it is translated to the left to f(x).
Thus, if we translate 2 units to the left, then using the form f(x) = a(x - h) + k, we will have;
f(x) = a(x + 2) + k
This is because;
h = horizontal shift
k = the vertical shift
a = the factor of stretch.
Now, we are told that it is translated 7 units down.
Downward translation denotes subtraction. Thus, k = -7 and our final translated function is;
f(x) = a(x + 2) - 7
14) Using the same concept above;
Translation of 5 units to the left means h = -5
Also, translation of 2 units up means that k = +2
Stretching by a factor of 3 means that a = 3.
Thus, from the form; f(x) = a(x + h) + k, we have;
f(x) = 3(x - 5) + 2

If one-third of a number is greater than five less than twice the number, which of the following is true? x < 3, x > -3, x > -3/5, x < 3/5
Answer: The correct option is
(A) x < 3.
Step-by-step explanation: Given that one-third of a number is greater than five less than twice the number.
We are to select the inequality that is TRUE.
Let the required number be represented by x.
Then, according to the given information,we have
[tex]\dfrac{1}{3}x>2x-5\\\\\\\Rightarrow x>3(2x-5)\\\\\Rightarrow x>6x-15\\\\\Rightarrow x-6x>-15\\\\\Rightarrow -5x>-15\\\\\Rightarrow 5x<15~~~~~~~~~~[\textup{since }-a>-b~~~\Rightarrow a<b]\\\\\Rightarrow x<\dfrac{15}{5}\\\\\Rightarrow x<3.[/tex]
Thus, the true statement is x < 3.
Option (A) is CORRECT.

Hailey paid $13 dollars for 1 3/7 kg of sliced salami.
Answer:
$9.1 per kg of sliced salami.
Step-by-step explanation:
We are supposed to find unit rate for the given scenario.
Hailey paid $13 dollars for 1 3/7 kg of sliced salami.
To find unit rate, we will divide total price by total weight.
[tex]\text{Unit rate}=\$13\div 1\frac{3}{7}\text{ kg}[/tex]
Convert mixed fraction to improper fraction:
[tex]\text{Unit rate}=\$13\div \frac{10}{7}\text{ kg}[/tex]
Convert to division problem by flipping the fraction as:
[tex]\text{Unit rate}=\$13\times\frac{7}{10}\text{ kg}[/tex]
[tex]\text{Unit rate}=\frac{\$13\times7}{10\text{ kg}}[/tex]
[tex]\text{Unit rate}=\frac{\$91}{10\text{ kg}}[/tex]
[tex]\text{Unit rate}=\frac{\$9.1}{\text{ kg}}[/tex]
Therefore, unit rate is $9.1 per kg of sliced salami.

The table shows the shipping costs for items of different values.
Which best describes the strength of the model?
a weak positive correlation
a strong positive correlation
a weak negative correlation
a strong negative correlation
Answer:
A strong positive correlation
Step-by-step explanation:
Since the dependent variable increases as the independent variable increases, this is a positive correlation.
Plotting these points, we can see that they form a nearly straight line. This makes it a strong correlation.
A strong positive correlation best describes the strength of the given model. So, option B is correct.
What is the correlation coefficient?The correlation coefficient is used to measure the strong relationship between the two variables.
The formula for the correlation coefficient
[tex]r= \frac{n(\sum xy)-(\sum x)(\sum y)} {\sqrt{ {[n\sum x^2-(x)^2] [n\sum y^2-(\sum y)^2]}}}[/tex]
We need to calculate the correlation coefficient and then make a conclusion about its value.

For a given input value q, the function f outputs a value r to satisfy the following equation. 11q-4=3r-6, Write a formula for f(q) in terms of q
Final answer:
To find the formula for f(q), solve the equation 11q-4=3r-6 for r. The steps include adding 6 to both sides and then dividing by 3, resulting in f(q) = (11q + 2) / 3.
Explanation:
To write a formula for f(q) in terms of q, we need to solve the equation 11q - 4 = 3r - 6 for r, the output of the function f. First, we add 6 to both sides to isolate the terms with r on the right side of the equation:
11q - 4 + 6 = 3r - 6 + 6
11q + 2 = 3r
Next, we divide both sides by 3 to solve for r:
(11q + 2) / 3 = 3r / 3
(11q + 2) / 3 = r
Therefore, the formula for f(q) is:
f(q) = (11q + 2) / 3
One of your friends gives you $10 for a charity walkathon. Another friend gives you an amount per mile. After 5 miles, you have raised $13.50 total. Write an equation that represents the amount y of money you have raised after x miles.
The initial amount given is $10, this represents a constant
Now another friends is willing to give an amount which is not fixed, hence it is dependent on the amount if miles we walk
Let this variable amount be x
We have walks 5 miles in total
We have raid is 13.5 total amount
Therefore he expression to represent the total amount we have made is given as
10+5x= 13.50
Let us solve for x
subtract 10 from both sides we have
5x= 13.5-10
5x= 3.50
divide both sides by 5 we have
x = 3.5/5
x= 0.7
Hence our friend gives us $0.7 per mile

draw the following scenario using a vertical number line.
mary climbed up a ladder 24 feet to the second story of her house. she then climbed back down
Final answer:
To draw Mary's ascent and descent on a ladder, create a vertical number line from 0 to 24 feet to signify the height of the second story, then illustrate arrows for the ascent and descent.
Explanation:
To visualize Mary's movement on a ladder, we will draw a vertical number line. Let's assume the bottom of the ladder is at 0 feet. We will draw a number line up to 24 feet to represent the height Mary climbs to reach the second story of her house. Then, since Mary climbed back down, we would show her descent back to 0 feet. Here is how you can draw the scenario:
Start with a vertical line.Mark the bottom as 0 feet (this is where Mary starts and finishes).Mark a point at 24 feet (this is where the second story of her house is).Draw an arrow pointing up from 0 to 24 to represent Mary climbing up.Draw an arrow pointing down from 24 back to 0 to represent Mary climbing down.By following these steps, you will have a clear representation of Mary climbing up and down her ladder on a vertical number line.

Answer: She cuts 2 pieces
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Length of the board: 3/4 yard Length of the pieces: 3/8 yardSo, to calculate the number of pieces we have to divide the length of the board (3/4) by the length of each piece (3/8)
Mathematically speaking:
3/4 ÷ 3/8 = (3x8) /(4x3)=24/12= 2 pieces

what is 0.279 times 53
Final answer:
To calculate 0.279 times 53, multiply 279 by 53 and then place the decimal point three places from the right of the product, resulting in 14.787. If rounding to two decimal places, the answer is 14.79.
Explanation:
To find the product of 0.279 times 53, we can follow the usual multiplication process. We multiply as if there were no decimal places, and then we count the total number of decimal places in both numbers to place the decimal in the correct position in the final answer.
0.279 has three decimal places, and 53 has none. After you multiply 279 by 53, count three places from the right of the resulting number to place the decimal point. So, if 279 times 53 equals 14787, then 0.279 times 53 equals 14.787.
Applying the rules of rounding, if we wanted to round the result to two decimal places we would get 14.79 since the third decimal place is a 7 which rounds up the second decimal place from 8 to 9.

The two stacks will be the same height when stacked to a height of 6 inches.
Explanation:To find the shortest height at which two stacks of boxes, one measuring 12 inches tall and the other measuring 18 inches tall, will be the same height, we need to find the least common multiple (LCM) of the two heights.
