Answer:
The required co-ordinate is (-2, -5).
Step-by-step explanation:
For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be: .
Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:
= (-2, -5)
The reflected point is (-2, -5).
Answer:
0,00027 grams!
Step-by-step explanation:
This is a scientific notation problem.
When a number is followed by a , it means that said number has one zero at the beginning.
In this case, the number is followed by , so that means that 2.7 has four zeros at the beginning. So, 2.7x
grams is equal to 0,00027 grams! (always the comma goes after the first zero).
