B.rotation 180° about the origin
C.translation 10 units right
D.reflection across the y-axis
The algebraic expression is a difference between two terms will be 5y - 7. Thus, the correct option is A.
Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.
An algebraic expression that is created by removing two terms is known as a difference between two terms. Only one of the suggested expressions corresponds to this description:
⇒ 5y - 7
The difference between the terms 5y and 7, which are being subtracted from one another, is represented by this equation.
Thus, the correct option is A.

The height of the office building is 99.2 meters
The given parameters are:
The above parameters can be represented using the following equivalent ratio
Express as fraction
So, we have:
Multiply both sides by 170
Rewrite as:
Hence, the building is 99.2 meters tall

Answer:
99.17m
Step-by-step explanation:
In the diagram, Marquis is at Point A and the flag pole is length DE, the building is of length BC.
Triangles ADE and ABC are therefore similar right triangles.
Applying this,
[TeX]\frac{|DE|}{|AE|}=\frac{|BC|}{|AC|}[/TeX]
[TeX]\frac{35}{60}=\frac{|BC|}{170}[/TeX]
|BC|=170*35÷60
|BC|=99.17m
