The easiest way to do this is to draw a blob where you need to end up and basically connect the origin (0,0) to the dot (or if there are changes, connect each of the dots in turn).
The difference between 11am and 2pm is 3 hours, so we will be going up to 3 on the x axis.
In this time he has travelled 12 kilometres, therefore we will go up to 12 on the y axis.
Putting this together, draw a dot at (3,12).
Now, draw a straight line from (0,0) to (3,12) - this is your line.
The slope of the line represents distance/time, i.e. how far he covered per unit time, which translates in layman's terms to speed i.e. how fast the hiker was going.
Answer:
Both are located on railroad lines
the question asks for similarities between Denver and Cheyenne. If you look at the map, both have the dotted line along them. In the key, the dotted lines represent railroads.
Answer: 15x^2 + 8x - 8
Step-by-step explanation:
1) Add them together
(15x^2 + 3x - 4) + (5x - 4)
2) Combine like terms
15x^2 + 8x - 8
Answer: OPTION B.
Step-by-step explanation:
The missing figure is attached.
For this exercise you need to use the Pythagorean Theorem. This is:
Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
In this case you can identify in the figure the triangle PRS, so the diagonal PR is the hypotenuse of the triangle PRS.
Then you can say that:
Therefore, knowing these values, you can substitute them into :
Finally you must solve for PR in order to find its value. This is:
