Step-by-step explanation:
Answer:
The circle at point-2 is not filled which means-2 is not included whereas the circle at point 5 is filled which means 5 is included in the interval of the given line.
The interval notation for the above line
<h3>-
2<x≤5</h3>
Answer:
Step-by-step explanation:
Rotation of any point in the form of (x, y) about the origin O through 180 degree in anticlockwise or counterclockwise direction, it will takes the new position (-x, -y)
i.e,
The rule of rotation about the origin through 180 degree is given by:
For example:
Let the point A(-4, 6) rotate by the rule
then;
⇒the coordinate of image of the point A is, (4, -6)
Therefore, the rule represents is,
We would find it by multiplying:
(x -6) * (x +3) * (x -5) =
x^3 -8x^2 -3x +90
The correct answer is A (7,9).
