A reflection over the x axis coupled with another reflection over the y axis leads to a rotation of 180 degrees.
In other words,
Start with point A. Reflect over the x axis to get point B. Reflect B over the y axis to get point C. To go from A to C, we can rotate A 180 degrees about the origin.
----------------
So this means that if we do those reflections and then do the rotation, then we end up back where we started. Wherever point A is located, the point A' will also be located at the same position with the same coordinates.

No solution
Step-by-step explanation:
Simplify the equation to solve for x.
-9(x+6)=-9x+108 Distribute
-9x-54=-9x+108 Combine like terms
+9x +9x
0-54=108 Combine like terms
+54 +54
0=162 No solution
You are measuring people and animals, so this is for sure two of your units. For the next units, you need to choose something big enough to hold a large number of these, so you would use square meters and acres. The answer is the third option: <span>number of people per square meter and number of animals per acre</span>
Answer:
Step-by-step explanation:
A road is perpendicular to a highway leading to a farmhouse d miles away.
An automobile passes through the point of intersection with a constant speed 
= r mph
Let x be the distance of automobile from the point of intersection and distance between the automobile and farmhouse is 'h' miles.
Then by Pythagoras theorem,
h² = d² + x²
By taking derivative on both the sides of the equation,
When automobile is 30 miles past the intersection,
For x = 30
Since 
Therefore,
Answer:
a^3-b^2
3^3-1-2^2
3*3*3-1/2*1/2*1/2
or
3*3*3-0.5*0.5*0.5
27-0.125
=26.875
