Reflection: the object is reflected (or "flipped") across a line of reflection, which might be the x-axis, y-axis, or some other line. Dilation: the object stays the same shape, but is either stretched to become larger (an "enlargement") or shrunk to become smaller (a "reduction").
The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
<h3>
How to rotate the triangle?</h3>
The coordinates of RST are given as:
R = (5,15)
S = (15,15)
T = (10,5)
The rule of 90° counterclockwise around the origin is:
(x,y) -> (-y,x)
So, we have:
R' = (-15,5)
S' = (-15,15)
T' = (-5,10)
Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

Answer:
192,000 grams
Step-by-step explanation:
turn 1,344 kilograms to grams, which gives u 1344000 grams
divide 1344000 by 7 and you get 192,000 grams. Hope this helped :)
Answer:
a) x^3y2
b) 6x^2y^3
Step-by-step explanation:
<h3>Answer: x < -2, choice B</h3>
===========================================
Work Shown:
10x + 18 < -2
10x + 18-18 < -2-18 ... subtract 18 from both sides
10x < -20
10x/10 < -20/10 ... divide both sides by 10
x < -2
