Answer:
Table 4th is showing the function that is decreasing only over the interval
Step-by-step explanation:
We have been given four tables below:
To determine the function that is decreasing only in the given interval
We will check the values after -1 in all four tables
The table in which values is only decreasing after -1 will be the table which shows a function is decreasing only.
In table 1 the value of x is increasing
In table 2 and 3 the value is increasing and then decreasing but we will consider only decreasing case
Therefore, Table 4th is correct.

Answer: The point (-10,-20) becomes (-8,-16) & point (15,25) becomes (12,20).
Step-by-step explanation:
When a point (x,y) is dilated by a scale factor k from the origin, then the new points become
The given rule of dilation : (x,y) →(0.8x, 0.8y)
The first point is (-10,-20), so its image will be
So, the point (-10,-20) becomes (-8,-16).
The second point is (15,25), so its image will be
So, the point (15,25) becomes (12,20).
Hence, the point (-10,-20) becomes (-8,-16) & point (15,25) becomes (12,20).
