Answer:
15
Step-by-step explanation:
We can find the greatest common factor by listing the factors of the 2 numbers, that is
Factors of 15 are 1, 3, 5, 15
Factors of 45 are 1, 3, 5, 9, 15, 45
The common factors are 1, 3, 5, 15
The greatest common factor is 15
Use the slope formula:
(y2 - y1)/(x2 - x1)
(x1, y1) = (-5, 1)
(x2, y2) = (-4, -4)
Answer:
(b) Both vertical and horizontal reflection
Step-by-step explanation:
The figure will be a horizontal reflection of itself about any vertical line through two of the smaller 6-pointed stars.
The figure will be a vertical reflection of itself about any horizontal line through two of the smaller 6-pointed stars.
the pattern has both vertical and horizontal reflection
__
<em>Additional comment</em>
A pattern will have horizontal reflection if there exists a vertical line about which the pattern can be reflected to itself. That is, there exists one (or more) vertical lines of symmetry.
Similarly, the pattern will have vertical reflection if there is a horizontal line about which the pattern can be reflected to itself. Such a line is a horizontal line of symmetry.
