The graph shows the amount of water that remains in a barrel after it begins to leak. The variable x represents the number of days that have passed since the barrel was filled, and y represents the number of gallons of water that remain in the barrel.
What is the slope of the line?
A. -2
B. -1/2
C. 7/16
D. 39/30
A = ( 15 , 15 )
B = ( 6 , 33 )
[tex]slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]
[tex]slope = \frac{33 - 15}{ 6 - 15} \\ [/tex]
[tex]slope = \frac{18}{ - 9} \\ [/tex]
[tex]slope = - 2[/tex]
Thanks for watching buddy good luck.

Answer:
A. -2
Step-by-step explanation:
took the test :))
Given the equation 9x - 3y - 27 in standard form. Show how you would
convert the equation into slope-intercept form - y = mx + b. You must
show your work to receive full credit. (3 points)
A standard form equation is when it is set up
Ax + By = C.
6x + 2y = 4
A slope-intercept form equation is when it is set up y=mx+b.
Y = - 3x + 2
In order to go from one form to another, all you have to do is change the order of the given numbers. First you want to move the Ax to the opposite side of the equation, by either adding or subtracting it. At this point your equation will be set up By = -Ax + C. Then you want to divide the B from the By and the rest of the equation. Therefore you will have y = - Ax/B + C/B. This is the same thing as the slope-intercept form, just a few of the letters are different.
Example 1:
Change from standard to slope form
8x + 4y = 16
8x + 4y = 16 first subtract 8x
4y = -8x + 16 then divide all by 4
y = -2x + 4 slope form
Example 2:
6x + 3y = 21
6x + 3y = 21 subtract 6x
3y = -6x + 21 then divide all by 3
y = -2x + 7 slope form

If 1 yard = 3 feet and 1 mile = 5,280 feet, how many yards are there in 4 miles?
Answer:
7040
Step-by-step explanation:
first find how many are in 1 mile by doing 5280/3 to get 1760.
second multiply 1760x4 to get 7040
If 1 yard = 3 feet and 1 mile = 5,280 feet, then there are 7,040 yards in 4 miles.
To convert miles to yards, we can use the given conversion factors:
1 mile = 5,280 feet
1 yard = 3 feet
We need to find how many yards are there in 4 miles.
Convert 4 miles to feet using the conversion factor:
4 miles × 5,280 feet/mile
= 21,120 feet
Now, Convert the 21,120 feet to yards using the yard-to-feet conversion factor:
21,120 feet / 3 feet/yard
= 7,040 yards
Therefore, there are 7,040 yards in 4 miles.

Camila is driving on a long road trip. She currently has 10 gallons of gas in her car. Each hour that she drives, her car uses up 1.75 gallons of gas. How much gas would be in the tank after driving for 3 hours? How much gas would be left after tt hours?
Answer:
gas left after 3 hours = 4.75
gas left after t hours = 10-1.75t
Step-by-step explanation:
According to DeltaMath "Since Camila uses 1.75 gallons of gas per hour, she would use 1.75 x 5, or 5.25 gallons in 3 hours. Since Camila started with 10 gallons in the tank, the amount of remaining after 3 hours would be 10-5.25 or 4.75 gallons. "

Which statement correctly compares the function shown on this graph with
the function y= 4x+2?
1 2 3 4 5
O A The function shown on the graph has a greater rate of change and
a higher starting point
O B. The function shown on the graph has a smaller rate of change, but
a higher starting point
O C. The function shown on the graph has a smaller rate of change and
a lower starting point
O D. The function shown on the graph has a greater rate of change but
a lower starting point
PLEASE ANSWER
Answer:
B. The function shown on the graph has a smaller rate of change, but a higher starting point.
Step-by-step explanation:
Rate of change = slope of a linear graph.
Given the linear function, [tex] y = 4x + 2 [/tex] , the rate of change here is represented by the slope of the line, which is 4.
Let's find the rate change of the function represented on the graph using slope formula:
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Use coordinates of any two points on the line. Let's take,
[tex] (0, 4) = (x_1, y_1) [/tex]
[tex] (1, 7) = (x_2, y_2) [/tex]
Rate of change = [tex] \frac{7 - 4}{1 - 0} = \frac{3}{1} = 3 [/tex]
Rate of change of the linear function of the graph = 3.
Thus the function on the graph has a smaller rate of change, than the function, y = 4x + 2.
The starting value of a function is the y-intercept, that is, the value of y, when x = 0. It is the point at which the line intercepts the y-axis.
The starting value of the linear function, y = 4x + 2 is 2.
The starting value of the function on the graph is 4. At this point, x = 0.
Thus, the function on the graph has a higher starting point.
The statement that correctly compares the function shown on this graph with the function y= 4x+2 is:
B. The function shown on the graph has a smaller rate of change, but a higher starting point.

Each driver is paid 8.65 per hour, if the field trip is going to lost 9.6 hours, how much will it cost to pay all of bus drivers?
Answer:
83.04
Step-by-step explanation:
First, you need to know how many drivers there are. But if the question doesn't tell you how many drivers then the answer would be 83.04 for one bus driver. If you forgot to add how many drivers then you can just multiply 83.04 to how many bus drivers then you get your answer.
Do the graphs of all rational functions have at least one asymptote or hole? Explain why or why not
A. No, a function may have neither asymptotes nor holes.
B. Yes, the function will have both a vertical asymptote and hole for any values that cause the denominator to be equal to zero.
C. Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero
D. Yes, the function will have either a horizontal asymptote or hole for any values that cause the denominator to be equal to zero.
Answer:
C. Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero
Step-by-step explanation:
We want to see if all rational functions always have at least one asymptote or hole.
The answer is C:
" Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero"
A rational function is something like:
[tex]f(x) = \frac{q(x)}{p(x)}[/tex]
Where q(x) and p(x) are polynomials.
The asymptotes or holes happen when the denominator is equal to zero and the numerator don't.
Now, in the cases where the numerator and denominator become zero for the same value of x, it means that we can factorize the polynomials and remove the common factor. So there we do not have a hole nor asymptote.
Now, because the denominator becomes equal to zero, this means that we are dividing by a reallly small value, then the quotient will tend to infinity or negative infinity, this means that we will have a vertical asymptote.
Then the correct option is C:
Yes, the function will have either a vertical asymptote or hole for any values that cause the denominator to be equal to zero
