Answer:
The correct option is 1 and 4 are correct.
Step-by-step explanation:
The dilation is the enlargement and comparison of a figure according to the scale factor from the given center of dilation.
The rule DO,2(x,y)(2x,2y) express the dilation with factor 2 and the center of dilation is origin. It shows the enlargement of the triangle. The sides of image is twice of the preimage.
In dilation the corresponding angles remains same and the corresponding sides are equal.
Therefore option 1 and 4 are correct.
Answer:
Arithmetic sequence.
Step-by-step explanation:
We have been given 9,5,1 and -3
We need to check what kind of sequence is this.
d is common difference we will check difference of consecutive terms.
We can see the difference between all the terms are same that is -4
So, this is an arithmetic sequence.
Arithmetic sequence is the sequence in which the difference between consecutive terms are same.
