Answer: 31.4 cm
Step-by-step explanation:
Answer:
A'(-1, 5), B'(-2, 3), and C'(-5, 4)
Step-by-step explanation:
Given the coordinate (x, y), if reflected over the y-axis, the resulting coordinate will be (-x, y):
Given the coordinates of the triangle expressed as:
A(1. 5), B(2, 3), and C(5, 4)
When these coordinates are reflected over the y-axis, the results will be:
A'(-1, 5), B'(-2, 3), and C'(-5, 4)
<em>Note that the x coordinates were negated while the y-coordinates remains unchanged</em>

Given:
The point is (-5,7).
To find:
The image of the given point after 90 degrees counter clockwise rotation.
Solution:
If a point rotated 90 degrees counter clockwise, then
Let the given point is P(-5,7). Using the above rule, we get
Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).
Answer:
x>-4
Step-by-step explanation:
if:-6<x-2
could be written as:x-2>-6
(collect like terms)
(sign changes)
x>-6+2
x>-4
