The two lines of reflection are and
Step-by-step explanation:
I will attach a file with the graph of the rectangle and the lines of reflection.
We know that RSTU is a rectangle with vertices at ,
,
and
The first step is to draw the vertices on the plane and them the rectangle.
The rectangle is a symmetrical figure. Therefore if we want to carry the rectangle onto itself using a line of reflection this line must goes through the centroid of the rectangle.
Given that we have a rectangle whose width is and its length is
its centroid will be place at
.
Looking at the graph and using this information we find that the two lines of reflection are and
.
-17 + n/5 = 33
First, we can start out by regrouping our terms. This will switch our fraction and number around and also make the original addition to subtraction.
Second, we can start out our goal by trying to get the variable (n) on one side by itself and to equal something. Let's begin by adding 17 to each side of the problem.
Third, we can now add the numbers on the right side of our problem. Simple. Add 33 + 17 to get 50.
Fourth, we now have to multiply both sides by 5. Why? We are getting rid of the fraction so that the variable can become by itself.
Fifth, our last step is to multiply 50 × 5. Use a calculator, long multiplication, etc. 50 × 5 = 250.
