Step-by-step explanation:
Graph the rational function f(x)=(3x-1)/(x-5)
To graph the rational function f(x) = (3x - 1) / (x - 5), follow these steps. Find the vertical asymptote(s) by setting the denominator equal to zero and solving for x.
x - 5 = 0
x = 5
The vertical asymptote of the function is x = 5.
Step 1: Find the horizontal asymptote by comparing the degrees of the numerator and denominator polynomials. Since the degree of the numerator (3x - 1) is 1, and the degree of the denominator (x - 5) is also 1, the horizontal asymptote is given by the ratio of the leading coefficients:
Horizontal asymptote: y = 3/1
Horizontal asymptote: y = 3
Step 2: Find the x-intercept by setting the numerator equal to zero and solving for x:
3x - 1 = 0
3x = 1
x = 1/3
The x-intercept is (1/3, 0).
Step 3: Find the y-intercept by setting x to zero and evaluating the function:
f(0) = (3 * 0 - 1) / (0 - 5)
f(0) = -1 / -5
f(0) = 1/5
The y-intercept is (0, 1/5).
Step 4: Find additional points to sketch the graph. Choose some x-values around the vertical asymptote (x = 5) and calculate the corresponding y-values. For example, you can use x = 4, x = 6, and x = 8.
x = 4:
f(4) = (3 * 4 - 1) / (4 - 5)
= 11 / -1
= -11
x = 6:
f(6) = (3 * 6 - 1) / (6 - 5)
= 17 / 1
= 17
x = 8:
f(8) = (3 * 8 - 1) / (8 - 5)
= 23 / 3
≈ 7.67
Step 5: Plot the points obtained from Steps 2 to 5 and draw the graph. The graph should approach the horizontal asymptote (y = 3) as it approaches the vertical asymptote (x = 5).
The graph of the rational function f(x) = (3x - 1) / (x - 5) should look like this:

What value of w makes the equation 145 = w + 27 true?
Answer:
118
Step-by-step explanation:
In the equation 145 = w + 27, you can solve for w by subtracting 27 from 145. That would give you 118. You can check this is correct by adding 27 to 118. 118 plus 27 = 145.
Answer:
118
Step-by-step explanation:
145 = w + 27
Switch the + sign before the 27 and switch into a minus and move it to the other side.
145-27=w
145-27=118
w=118
The ratio of blue marbles to red marbles in a box is 3 to 2. if there are 12 blue marbles in a box then how many red marbles are there?
Answer:
8 red marbles.
Step-by-step explanation:
The ratio is 3:2, blue to red. If there's 12 blue marbles and the first part of the ratio's 3, then:
12/3=4
Then you take the 4 and multiply it by 2, the second half of the ration to get 8.
And so, the answer's 8. If you divide 12:8 by 4 each you get your original ratio of 3:2, so that's your way to check.

Step-by-step explanation:
Can you hear me now cost function: y=0.15x+50.75
24 Hour Calls cost function: y=0.9x+24.5
Set two equations equal to each other because we want to find the time (x value) that make the cost (y-value) equal
0.15x+50.75=0.9x+24.5
0.75x=26.25
x=35mins

30 POINTS FOR THIS...Bus Stop: A graph has time (minutes) on the x-axis, and distance (miles) on the y-axis. A line goes through points (0, 5), (6, 8), and (12, 11).

Seth is comparing scenarios to determine which starting point he should get dropped off at to get him to school faster. Seth's house is 17 miles from school.
In which scenario does Seth start closer to school?
In which scenario does Seth travel at a greater speed, and what was the rate?
Answer:
In which scenario does Seth start closer to school?
bus stop, 5 miles from home
In which scenario does Seth travel at a greater speed, and what was the rate?
friend’s house, 2 miles every 3 minutes
The speed of Seth when he travels from the Bus stop will be faster. Because the speed is greater.
What is an average speed?The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.
We know that the average speed formula is given as,
Average speed = Total distance / Total time
The speed of Seth when he travels from the Bus stop will be
Average speed = (8 - 5) / (6 - 0)
Average speed = 3 / 6
Average speed = 0.5 miles per hour
The speed at Seth when he travels from the Friend's house will be
Average speed = (8 - 4) / (9 - 3)
Average speed = 4 / 6
Average speed = 0.33 miles per hour
The speed of Seth when he travels from the Bus stop will be faster. Because the speed is greater.
More about the average speed link is given below.

If sales tax is 9%, what is the total price Sami paid? Round to the nearest cent, if necessary.
Answer:
$19.23
Step-by-step explanation:
First, add the prices of all 5 comics together. That should equal $17.63. The tax is 9% so that would be 1.5867 or $1.60. In total, Sami paid $19.23.
