Answer:

n = 7

Step-by-step explanation:

3n - 12 = 9

3n = 9 + 12

3n = 21

n = 21 ÷ 3

n = 7

Slope -3/7 and goes thru (9,-11)
goblinko [34]

The equation of line is ,

\begin{gathered} (y-(-11))=\frac{-3}{7}(x-9) \\ y+11=\frac{-3}{7}x+\frac{27}{7} \\ y=\frac{-3}{7}x+\frac{27}{7}-11 \\ y=\frac{-3}{7}x-\frac{50}{7} \end{gathered}

Describe a similarity transformation that maps △ABC
PIT_PIT [208]

Let's start with a picture.

We see RST is smaller, and BC is parallel to but in the opposite direction to its corresponding segment ST.  Both have slope -1.

If we look at the difference of points (technically called vectors but we don't have to go there) we get

C-B=(-2,2)

T-S=(1,-1)

Without further calculation we can see T-S is half the length of C-B.

The problem asks for a dilation followed by a reflection.   We know the dilation scale is k=1/2 because the new triangle is half the size.  

After dilation we get A'B'C':

A'(3,2), B'(-1,0), C'(-2,1)

We see now we need a reflection that flips the coordinates x and y.  That's the +45° line through the origin, namely y=x.

Answer: k=1/2, y=x
