Question

Solve the function f(5): 2x+4x/3x​

Answer 1

Explanation:

f(5) : (2x + 4x)/3x

= [2(5) + 4(5)]/3(5)

=10 + 20/15

=30/15

=2

Answer 2

f(5) = 11 and 1/3, or approx. 11.33

Explanation:

`f(x) = 2x + (4x)/(3x)`

We can divide away x in 4x/3x:

`f(x) = 2x + (4)/(3)`

To calculate f(5), we substitute x with 5:

`f(5) = 2 * 5 + (4)/(3) = 10 + (4)/(3) = 11 (1)/(3)`

Answer: 11 and 1/3, or approx. 11.33
