A) (0,0) and (3,1)
1-0 divided by 3-0
Slope is 1/3
the slope represents the relationship between x and y
b) (6,2) and (-3,-1)
-1-2 divided by -3-6
Slope is 1/3
c) yes, the two triangles represent the same slope as all of the four points used are collinear (on the same line), making all the slopes equal.
Basically you just have to plug in g(x) wherever you see an x in the equation f(x) since x is f(x) you just substitute it . So f(g(x))=2x+3
You then just have to solve for 0
0=2x+3
Subtract 3 from both sides
-3=2x
Divide by 2
X=-3/2
Answer:

- <em>You would need fewer the unit</em><em><u> </u></em><u>kilometer (km) </u><em>to measure a tree.</em>
Explanation:
In the internet you can find that the greatest height of a tree is aobut 115 meters.
Thus, you would never expect to find a tree measuring kilometers or miles.
If you used kilometers as unit, the measure of the tallest tree woul be about 0.115 km (115 meter divided by 1,000).
Most of the trees meausre in the range of 1 to 20 meters. That would be 0.001 km to 0.020 km.
Thus, kilometer is not a unit that you would need to measure a tree. You'd rather use centimeters, when the tree is small, and meters for most of the trees. You may also use feet, since 1 meter is about 3.28 feet, or even yards, since 1 yard is equal to 3 feet.
Answer:
The difference is that a rate is a comparison of two numbers with different units, whereas a ratio compares two numbers with the same unit.
