Josie read 246 pages of a book last month her older brother says he read about 3 to 4 times as many pages as Josie explain why 2500 is not a reasonable estimate for the number of pages that Josie's brother read

2500 is not a reasonable estimate.

Step-by-step explanation:

We are given the following in the question:

Number of pages read by Josie = 246

Pages read by older brother = 3 to 4 times as many pages as Josie

If x represents the number of pages read by her brother, we can write:

Putting values, we get,

Since, 2500 does not lie in this interval

Thus, 2500 is not a reasonable estimate for the number of pages that Josie's brother read.

45

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
