Mark and jessica are each making a linear model to predict the population of squirrels in the town park. the are both using the same data points to find an equation of the line of best fit: the squirrel population, p, in 2002 and the squirrel population, q, in 2011. mark is using the year as the x-value, and he represents his data as (2002, p) and (2011, q). jessica is using the years since 2000 as her x-value, and she represents her data as (2, p) and (11, q).

which statement best describes how their prediction equations compare?

a. their equations have the same x-coefficients and y-intercepts.
b. their equations have different x-coefficients and y-intercepts.
c. their equations have different y-intercepts but the same x-coefficients.
d. their equations have the same y-intercepts but different x-coefficients.

 The answer is (C) Their equations have different y-intercepts but the same x-coefficients.

Step-by-step explanation:  Given that Mark and Jessica are each making a linear model to predict the population of squirrels in the town park.

Since (2002, p) and (2011, q) are two points on Mark's data, so the linear equation representing the population of squirrels is given by

Also, (2, p) and (11, q) are two points on Jessica's data, so the linear equation will be

Comparing equations (i) and (ii), we can say that Mark and Jessica's linear equations have different y-intercepts but same x-coefficients.

Thus, (C) is the correct option.

answer: i think it's a

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
