Answer:
The equation that models the relationships between
, the number of hours Mark reads, and ,
the number of pages of the book he reads is:

Step-by-step explanation:
Given:
Mark reads 42 pages every
hour.
The number of hours is given by = 
The number of pages is given by =
The equation can be modeled as:

where
represents rate of change and
represents the y-intercept or the initial value.
Rate of change =
The initial value
as Mark starts reading from 0.
So, the equation is:

I would decide which unit to use to measure my math book by looking at the size. Dont use feet on a small book
Answer:
R' = (-2, -3)
Step-by-step explanation:
When a figure undergoes a 180degree rotation, both the (x) and (y) coordinates are multiplied by (-1). The coordinates of the given point are (2, 3). Multiply both of these numbers to fine (R'), that is point (R) after it undergoes its rotation. The coordinates of (R') are (-2, -3).

Answer:
There are 18 women in the class
Step-by-step explanation:
First of all this is a ratio topic and to solve it one needs to know that ratios are fractions so to solve it we will find first the sum of the fractions which is 3+1 and =4. Fully recognising through the question that the fractions or relation of the women to the men in the classroom is in a 3:1 ratio, we should multiply the fraction with the total number of people in the class which bring forth the result as 18!
