Answer:
A. and
Step-by-step explanation:
Given:
Vertices of triangle RST are and .
Rotation is 90° about the center O(0,0). The rotation is counter-clockwise as the angle of rotation is positive.
Now, the co-ordinate rule for 90° rotation counter-clockwise is given as: →
and values interchange their places with becoming negative when interchanged.
So, →
→
→
⇒ →
Therefore, the image of the vertices are and .
Answer:
x^2+x+1
Step-by-step explanation:
(x-2)+(x^2+3)=x-2+x^2+3=x^2+x-2+3=x^2+x+1
You would x out the 3 and look at the 2.6 then u would round it to 10 so ur answer would be 2.10
Write out 5t^2 3t 5t^2
-------- . Invert --------- and multiply ---------- by the result:
8x^2 (x^2) 8x^2
5t^2
multiply ---------- by the result: 5t^2 5*x^2 25 t^2 x^2
8x^2 ------- * --------- = ----------------
8x^2 3t 8x^2 (3t)
Reducing this, we get 25t
-------
24x
