Answer:
Step-by-step explanation:
To express the quantities given in ratio language, we need to determine the ratio between the number of books read by each person.
Lauren: For every 10 books Jamar read, Lauren read 40 books. This can be expressed as a ratio of 40:10, which simplifies to 4:1.
Henry: For every 10 books Jamar read, Henry read 70 books. This can be expressed as a ratio of 70:10, which simplifies to 7:1.
Jamar: Since Jamar is the reference point for the ratios, the ratio for Jamar will always be 1:1.
So, the ratios for the number of books read in a year are:
Lauren: 4:1
Henry: 7:1
Jamar: 1:1
These ratios represent the relative quantities of books read by each person in a year, simplifying the comparison between their reading habits.

B. Dilation centered at P, followed by reflection across the y-axis and then the line y = -x + 5
C. Translation (x,y) -> (x+4, y+2), followed by dilation centered at Q
D. Dilation (x+y) -> (3/5x, 3/5y), followed by dilation centered at P
E. Reflection over x-axis followed by rotation of 270 degrees
Answer:
Step-by-step explanation:
Centerat (-1, 2).
Radius of 3.
Center at (3, 4).
Radius of 5.
To carry one circle onto the other, their centers and radius must be the same.
So, circle P must be shifted from (-1, 2) to (3, 4), that means the translation is 4 units to the right side and two units upside, this is the first transformation.
The second transformation must be about stretching the circle P, from a radius of 3 to a radius of 5.
Therefore, the right answer is B.
Answer: Option b and Option c
Answer:
reflection across the y-axis and translation 2 units right. :)
Step-by-step explanation:
It seems to be a reflection across line x = 1.
