Question

A company is selecting students for interviews at the career fair. The number of students selected from university A is given by Rx) = 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
B.
C.
D.
h(x) = 6x + 13
h(x) = -2x + 3
h(x) = 2x - 3
f(x) = (4x + 5)(2x + 8)

Answer 1

6x + 13.

Explanation:

That is the sum of R(x) and g(x)

= 4x + 5 + 2x + 8

= 6x + 13.

Answer 2

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

Explanation:

We are given that,

Function representing number of students from A,

Function representing number of students from B,

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

So, we have,

Total number of students =

i.e. Total number of students =

i.e. Total number of students =

i.e. Total number of students =

Hence, the function representing the total number of students in the fair is .

Thus, option D is correct.
