Question

PLEASE HELP!!!
A company is selecting students for interviews at the career fair. The number of students selected from university A is given by f(x) = 4x + 5, where x represents the number of days of the fair. The number of students selected from university B is given by g(x) = 2x + 8.

Which function best describes the total number of students selected at the career fair?

A) h(x) = (4x + 5)(2x + 8)
B) h(x) = 2x - 3
C) h(x) = -2x + 3
D) h(x) = 6x + 13

Answer 1

The right answer is D h(x)= 6x+ 13

Answer 2

Answer:

D) $h(x)=6x+13$.

Step-by-step explanation:

We are given that,

Function representing number of students from A, $f(x)=4x+5$

Function representing number of students from B, $g(x)=2x+8$

It is required to find the total number of students in the fair.

So, we have,

Total number of students = $f(x)+g(x)$

i.e. Total number of students = $(4x+5)+(2x+8)$

i.e. Total number of students = $(4x+2x)+(5+8)$

i.e. Total number of students = $6x+13$

Hence, the function representing the total number of students in the fair is $h(x)=6x+13$.

Thus, option D is correct.
