<h3>
Answer: D. y = -x</h3>
======================================================
Explanation:
Point T is at (-2,1)
When we reflect it over the line x = 0, aka the y axis, we use the rule 
so T(-2,1) becomes T ' (2, 1). The x coordinate flipped in sign, while the y coordinate stays the same.
Then the final transformation is reflecting over y = -x using the rule 
. Therefore, the point (2,1) moves to (-1, -2) which is where T'' is located in the diagram.
You apply the same two transformations for the points R and S to get R'' and S'' respectively.
Note: A composition of two reflections, where the lines of reflection aren't parallel, form a rotation. In this case, we have a 90 degree counterclockwise rotation when going from triangle RST to triangle R''S''T''.
They were up 15+0+25+10-20-10=20. The sum was 20 :)
Answer:
14 cm²
Step-by-step explanation:
Obtuse angle: more than 90° and less than 180°
The formula for the area of an obtuse triangle is the same as that for any triangle:
- area of a triangle = 1/2 x base x height
Therefore, given:
⇒ area = 1/2 x 4 x 7 = 14 cm²
Answer:
x=7
Step-by-step explanation:
I got this because it is rise over run
The missing number would be 3, and if you add that three to 4 you get 7. which means that the answer is...
(7,12)

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
I am unable to read all of the options in the picture you provided but I hope this helps! (:
