Question
(𝑥, 𝑦) → (−𝑥, 𝑦) represents
- Reflection in the X-axis
- Reflection in the Y-axis
- Reflection in the x = y
Hint:
In reflection, mirror image of the original figure is created about axis of reflection
The correct answers are: Reflection in the X-axis, Reflection in the Y-axis
We know that reflection is mirror image of given point where axis of reflection act as plain mirror. So, when a point is reflected about y – axis, then the y – coordinate remains same, but the x – coordinate becomes negative.
It is given that (𝑥 , 𝑦) → ( - 𝑥 , 𝑦).
i.e. y – coordinate is same and x – coordinate becomes negative.
Hence, reflection in the y – axis.

In the equation above, what is the value of s when t= -1 ?
Note:
Instead of adding 1 on both sides, we can also understand the concept by taking _1 of the left hand side on the right hand side and then the sign changes to +1 . Similarly, instead of dividing by 2, we can understand it by saying that we take 2 from the left hand side to the right hand side, and here it becomes division.
Thus, addition becomes subtraction and vice-versa when taken from left hand side to right hand side or the opposite way; and multiplication becomes division and vice-versa. Be careful, 0 is never taken in the denominator.

The equation above can be used to model the population, in thousands, of a certain city t years after 2000. According to the model, the population is predicted to increase by 0.5% every n months. What is the value of n?
Note:
We need to understand what each quantity given in the equation
represents. For example, the population in year 2000 is 2,15,000. After 3 tears, that is, in year 2003, the population becomes 
thousand which is 216075.
