Acompany 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)

6x + 13.

Step-by-step explanation:

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

= 4x + 5 + 2x + 8

= 6x + 13.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
