Answer:

Third item in the list

Step-by-step explanation:

Third function:  f(x) = x + 9.  If we substitute 14 for x, we get f(14) = 14 + 9 = 23.

Step-by-step explanation:

Answer:

[tex] \huge\: f = \frac{61}{7} \: or \: 8\frac{5}{7} [/tex]

Step-by-step explanation:

to understand this

you need to know about:

  • equation
  • PEMDAS

given:

  • [tex]f + 14 \frac{2}{7} = 23[/tex]

to find:

  • [tex]f[/tex]

let's solve:

[tex]step - 1 : define[/tex]

[tex]f + 14 \frac{2}{7} = 23[/tex]

[tex]step - 2 : solve[/tex]

  1. [tex]cancel \: 14 \frac{2}{7} \: from \: both \: sides \\ f + 14\frac{2}{7} - 14 \frac{2}{7} = 23 - 14\frac{2}{7} \\ f = 23 - 14 \frac{2}{7} [/tex]
  2. [tex]simplify \\ f = 23 - \frac{100}{7} \\ \frac{161 - 100}{7 } \\ \frac{61}{7} [/tex]

[tex] \therefore \: f = \frac{61}{7} \: or \: 8\frac{5}{7} [/tex]
