Answer:
U (2,-1)
Step-by-step explanation:
if you replace x to 2, your answer will come out to be -1
Answer:
From the graph: we have the coordinates of RST i.e,
R = (2,1) , S = (2,-2) , T = (-1,-2)
Also, it is given the scale factor
and center of dilation C (1,-1)
The mapping rule for the center of dilation applied for the triangle as shown below:

or
or

Now,
for R = (2,1)
the image R' =
or

⇒ R' =
For S = (2, -2) ,
the image S'=
or

⇒ S' =
and For T = (-1, -2)
The image T' =
or

⇒ T' = 
Now, label the image of RST on the graph as shown below in the attachment:
Answer:
Legenth times width
Step-by-step explanation:
Answer:
k = 5
Step-by-step explanation:
-2k = k - 7 - 8
Combine like terms
-2k = k - 15
add 15 to both sides
-2k + 15 = k
Add 2k to both sides
15 = 3k
Divide both sides by 3
k=5
Hope this helps!
X+y=155. Y= -x+155
1.50x +4(-x+155)= 520
1.50x-4x+620=520
-2.5x =-100
X= 40. Y=110
