Given the following expression:
\(\frac{1-\frac{1}{x}}{3+\frac{1}{x}}\)We will simplify the given expression as follows:
Multiply both the numerator and the denominator by x to eliminate the denominators of each part
\(\frac{1-\frac{1}{x}}{3+\frac{1}{x}}=\frac{x(1-\frac{1}{x})}{x(3+\frac{1}{x})}=\frac{x-x*\frac{1}{x}}{3x+x*\frac{1}{x}}=\frac{x-1}{3x+1}\)So, the answer will be:

The function g( x ) is translated to the left by 9 units and down by 5 units.
Given data ,
Let the first function be represented as f ( x )
where the value of f ( x ) = | x |
Let the translated function be g ( x )
where the value of g ( x ) = | x + 9 | - 5
A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.
On translating to the left , f ( x + a )
So , the function f ( x ) is translated 9 units to the left by f ( x + 9 ) = | x + 9 |
Now , when the function is translated 5 units down , f ( x ) - 5
So , the translated function is g ( x ) = | x + 9 | - 5
Hence , the function is translated to the left by 9 and up by 5 units.

Two friends, Robert and Sasha, are walking in opposite directions around a marsh that has a 15-mile perimeter. If Robert walks twice as fast as Sasha, how fast does Robert walk if they
meet after 2.5 hours?
Answer:
2 times faster than Sasha
Step-by-step explanation:
Because it is 15 miles and it doesn't matter how fast Sasha walks its just that times 2.5 which in this case gets us 2 times faster assuming that Sasha is walking 5 miles an hour.
Robert's speed if they meet after 2.5 hours is 4.8 mph as calculated below.
How to solveSince the perimeter of the marsh is 15 miles, and Robert and Sasha meet after 2.5 hours, they each walked 15 / 2.5 = 6 miles in that time.
Since Robert walks twice as fast as Sasha, Sasha walked 6 miles while Robert walked 2 * 6 = 12 miles.
Therefore, Robert's speed is 12 miles / 2.5 hours = 4.8 mph.

Answer:
15 miles
Step-by-step explanation:
Speed of John biking = 10 miles per hour
Time taken by John to travel the route = 1.5 hours
We know that
distance = speed * time
now that we know time and speed for John
we can distance by using the above formula
distance = 10 miles per hour* 1.5 hour = 15 Miles
Thus, the route was 15 miles long.

Question A survey asked 10 boys and 10 girls how many text messages they sent the previous day. The number of texts are given in the line plots. Select from the drop-down menus to complete each statement. The data set with the greater range is Choose... . The median Choose... .
The data set with the greater range is greater for girls. The median is greater for girls.
The range of a dataset is the difference between the maximum and minimum values in the set.
The median is the middle value in a sorted dataset, or the average of the two middle values if the set has an even number of elements.
To determine which dataset has a greater range, you need to compare the difference between the highest and lowest values of the two datasets.
To determine which dataset has a larger median, you need to sort the datasets and find the middle value(s).
The range for boys is 60 as for girls the range is 80. The median for boys is 90 and for girl 110.
Hence, the data set with the greater range is greater for girls. The median is greater for girls.

What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
It is given that,
Length of road = 9 miles
From the condition,
Mai ran 1/4 of the length of her road
Mai ran = 1/4 × length of her road
Mai ran = 1/4 × 9
Mai ran = 2.25 miles.

what are the domain and range of the function?
The domain and range are the set of all real numbers, so:
Domain: x ∈ R
Range: x ∈ R
Thus, the correct option is the second one
What are the domain and range of the function?
For any function y = f(x), we define the domain as the set of the possible values of x (the ones on the horizontal axis) and the range is the set of the possible values of y (vertical axis).
In this case, we have a linear equation (you can see that the lines extend to the bottom left and the top right)
So both domain and range are the sets of all real numbers.
Thus, the correct option is the second one.

What is Exponentiation ?
Exponentiation is a mathematical operation that involves the base number (b) and the exponent (or power) number (n), and is represented as bⁿ. Its pronunciation is "b (raised) to the (power of) n." Exponentiation corresponds to repeated base multiplication where n is a positive integer; so, bⁿ is the result of multiplying n bases.

Select the correct answer. Which equation matches the function shown in the graph? A waveform on a coordinate plane starts from the y-axis at 1 unit and passes through (pi, minus 1), (2 pi, 1), and (3 pi, minus 1) and intercepts the x-axis at pi by 2, 3 pi by 2, 5 pi by 2, and 7 pi by 2.
The correct equation that matches the given graph is y = cos(x) + 1.
To determine the equation that matches the given graph, we can observe the key features and points provided.
The waveform starts from the y-axis at 1 unit: This suggests that the function has a vertical shift of 1 unit upwards.
The waveform passes through (π, -1), (2π, 1), and (3π, -1): This indicates that the function oscillates between the values of -1 and 1 as x increases.
The waveform intercepts the x-axis at π/2, 3π/2, 5π/2, and 7π/2: This suggests that the function has zeros or x-intercepts at these values.
Based on these observations, the function can be represented as a cosine function.
The cosine function with a vertical shift of 1, oscillating between -1 and 1, and having zeros at π/2, 3π/2, 5π/2, and 7π/2 is:
y = cos(x) + 1

It takes Sara 5 1/2hours to drive to her aunt's
house. She has already driven 3 1/2 hours.
How much longer does Sara have left to
drive?
Answer:
2 hours
Step-by-step explanation:
To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:
5.5 - 3.5 = 2.0
Meaning, Sara has 2 hours left to drive

Answer:
162
Step-by-step explanation:
to find the surface area of the rectangles do base x height
5 x 10 = 50
there are 3 sides on a triangle so do 50 x 3 = 150
now we need to find the area of the triangles
the formula for the surface area would be base x height ÷ 2
3 x 4 = 12
12 ÷ 2 is 6
because there are 2 triangles you would need to multiply it by 2
6 x 2 is 12
add it all together
12 + 150 is 162
