The answer is the first option.
Step-by-step explanation:
Remember
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
Plug in for each!
[tex]m = \frac{ 1 - 2}{4 - 8} = \frac{ - 1}{ - 4} = \frac{1}{4} [/tex]

A traveler is walking on a moving walkway in an airport. The traveler must walk back on the walkway to get a bag he forgot. The traveler's ground speed is 1 fts against the walkway and 5 ft/s with the walkway. What is the traveler's speed off the walkway? What is the speed of the moving walkway? The traveler's speed off the walkway is ft/s.
Answers
Answer: here is your answer
Step-by-step explanation:
You can put this solution on YOUR website!
+t+ = traveler's speed in ft/sec
+w+ = walkway's speed in ft/sec
given:
+t+-+w+=+2+
+t+%2B+w+=+6+
-------------
Add the equations
+2t+=+8+
+t+=+4+
and
+t+%2B+w+=+6+
+4+%2B+w+=+6+
+w+=+2+
The traveler's speed off the walkway is 4 ft/sec
The speed of the moving walkway is 2 ft/sec
Sheleah and her family are planning a trip from Los Angeles, California to Melbourne, Australia. While booking her family's plane tickets, she notices on the itinerary that the airline is offering a sixteen hour straight flight from Los Angeles to Melbourne on a Boeing 747-8 Intercontinental Jet. In an effort to learn more about the capabilities of the Jet, Sheleah does a little research and stumbles upon the following graph and facts about the Jet's gasoline consumption.
GRAPH IN SCREENSHOT
The Boeing 747-8 Intercontinental Jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel.
Using the graph, approximate the Jet's average gas consumption, in gallons per hour, during the sixteen hour flight from Los Angeles, California to Melbourne, Australia. In your final answer, include all of your calculations.
Answers
26375
On the graph, it tells you how much fuel is left after 2 hours of the journey.
If we take 422,000 and subtract 369,250 from it we get 52,750. However, this is how much gas is used in 2 hours, so to find one hour we need to divide by 2, getting us 26,375.
Therefore, the Jet uses 26,375 gallons per hour during the 16 hour trip from Los Angeles, CA to Melbourne, Australia.
Keisha is reading a 310 page book at a rate of 23 pages per day.Use a point-slope equation to determine how many pages she will have left to read after reading the book for 10 days. She will still have [ ] pages left to read after 10 days.
Answers
Answer:
80 pages
Step-by-step explanation:
Point slope Equation is :
y = mx + c
In the above question
y = 310 pages
x = number of days = 10 days
m= 23 pages per day
c = ?? Unknown
c = y - mx
c = 310 - 23 × 10
c = 310 - 230
c = 80 pages
She will still have 80 pages left to read after 10 days
Please do elimination method 2x-9y=-36
-14x+18y=-18
Answers
Answer:
The solution to the system of equations will be:
[tex]x=9,\:y=6[/tex]
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}2x-9y=-36\\ -14x+18y=-18\end{bmatrix}[/tex]
Multiply 2x-9y=-36 by 7
[tex]14x-63y=-252[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}14x-63y=-252\\ -14x+18y=-18\end{bmatrix}[/tex]
Adding both equations
[tex]-14x+18y=-18[/tex]
[tex]+[/tex]
[tex]\underline{14x-63y=-252}[/tex]
[tex]-45y=-270[/tex]
solve -45y = -270 for y
[tex]-45y=-270[/tex]
divide both sides by -45
[tex]\frac{-45y}{-45}=\frac{-270}{-45}[/tex]
Simplify
[tex]y=6[/tex]
For 14x-63y = -270 plug in y = 6
[tex]14x-63\cdot \:6=-252[/tex]
[tex]14x-378=-252[/tex]
Add 378 to both sides
[tex]14x-378+378=-252+378[/tex]
Simplify
[tex]14x=126[/tex]
Divide both sides by 14
[tex]\frac{14x}{14}=\frac{126}{14}[/tex]
Simplify
[tex]x=9[/tex]
Therefore, the solution to the system of equations will be:
[tex]x=9,\:y=6[/tex]
