Answer: 4/5 book per hour
Step-by-step explanation: in this question, we are to rewrite (2/5)/(1/2) as unit rate.
To write this as a unit rate, what we need to do is to divide 2/5 by 1/2.
That means 2/5 divided by 1/2
Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour
The answer is SAS

Answer: *An image created by a reflection will always be congruent to its pre-image.
*Corresponding angles and segments are always congruent in a reflection of a figure.
*An image and its pre-image are always the same distance from the line of reflection.
Step-by-step explanation:
Since, reflection is a rigid transformation therefore, it preserves the shape of the figure and create congruent images.
And we know that if if two figures are congruent then their corresponding angles and sides are congruent.
Reflection maps a figure to create its mirror image, and the distance of object and image is always equal from the mirror, therefore "An image and its pre-image are always the same distance from the line of reflection."

Answer: D) 5/2</h3>
==================================================
Explanation:
The parabola is symmetric around its vertex. This means that the roots are the same horizontal distance away from the vertex. Furthermore, we can apply the midpoint formula on the given roots to find the x coordinate of the vertex.
Find the midpoint of 2 and 3 to get (2+3)/2 = 5/2
Note: 5/2 = 2.5
Answer:
B'(- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
