Answer: 8
Work Shown:
f(x) = 5x - 7
f(3) = 5(3) - 7 .... every x replaced with 3
f(3) = 15 - 7
f(3) = 8
Option - D is ✔ (8)
[tex] \: [/tex]
Given :
- f(x) = 5x - 7
- x = 3
To Find :
- What is the value of x ?
Calculating the value of x :
[tex]\sf : \implies \: 5x - 7[/tex]
[tex]\sf : \implies \: 5(3) - 7[/tex]
[tex]\sf : \implies \: 15 - 7[/tex]
[tex]\bf : \implies \: 8[/tex]
Hence,
[tex] \implies \boxed{ \bf \: \therefore \: The \: value \: of \: x \: is \: 8 \: } \\ \\ [/tex]
