Y=5x+42
subtract 5x from both sides
-5x+y=42
multiply by -1
5x-y=-42
In standard form, Ax+By=C, the variable A cannot be a negative. However, this is not an option so go with c.
The Angle of rotation of the given regular pentagon after undergoing rotational transformation is; 72°
<h3>How to find the angle of rotation?</h3>
We are told that the image is a perfect pentagon that all its' sides are all equal with no uneven sides.
Now, A figure is said to have rotational symmetry if it looks exactly the same after rotating it some angle less than 360° which is a full rotation.
Now, a regular pentagon will have a rotational symmetry of order 5 because it will look the same after 5 turns.
Thus;
Angle of rotation = 360/5
Angle of rotation = 72°

Answer:
A
Step-by-step explanation:
To express 4/5 as a decimal, you divide 4 by 5. Here is long division image at the bottom. You can just input it into a calculator (4 divdie 5) or notice that 4/5 = 8/10 = 0.8.
