RSTU is a rectangle with vertices at R(-3,1), S(1 ,1), T(-3,3) and U (1, 3). Describe two lines of reflection that would carry t
miss Akunina [59]

Answer:

The two lines of reflection are x=-1 and y=2

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 R=(-3,1) , S=(1,1),

T=(-3,3) and U=(1,3)

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 a and its length is b its centroid will be place at (\frac{a}{2},\frac{b}{2}).

Looking at the graph and using this information we find that the two lines of reflection are x=-1 and y=2.

Kim's softball team is playing in the championship game. They are losing by a score of 17 to 6. There are 4 innings to go. Kim w
n200080 [17]
They are 11 runs down. 17 - 6 = 11 They have 4 at bats to go. 3 runs each of 4 at bats = 12 runs. 12 new runs plus 6 you have scored will give you 18 runs, if you do not allow your opponent any more runs! If you allow your opponents to score , you will need to add those to your answer!
